JP4844577B2 - Karaoke system, server, karaoke terminal, and music proposal method - Google Patents

Description

  The present invention relates to a karaoke system having a function of proposing music suitable for a user to sing.

In recent years, in a karaoke system, a score obtained as a result of a user's singing is ranked in relation to a plurality of other users, and the result is notified (for example, Patent Document 1). reference).
JP-A-11-338481

  However, at present, only the ranking after the singing is notified, and even if there is a request that the user wants to select a song that can obtain a high ranking and start singing, it can respond to such a request. It was not a thing.

  The present invention has been made to meet such a demand, and an object of the present invention is to provide a technique for enabling a user to select a song that can obtain a high ranking.

  In order to solve the above problems, a karaoke system including a server and one or more karaoke terminals respectively connected via a network may be configured as a first configuration (claim 1) shown below.

  In this configuration, when the server receives a proposal request with identification information (for example, a user ID such as a membership number) assigned to a specific user from the karaoke terminal, the identification information related to the proposal request For each piece of music stored in the storage unit as a scoring result when a user (hereinafter referred to as “requesting user”) sings the music, the music is stored in the storage unit as a scoring result of each of the plurality of users singing. Among the music stored in the storage unit as a scoring result when the requesting user sings the music, distribution specifying means for specifying the distribution of the scores related to the scoring per unit score (hereinafter referred to as “scoring distribution”) Each of the songs in which the score as a result of scoring of the music is in an area in which the number of samples is greater than or equal to a predetermined number in the scoring distribution specified by the distribution specifying means for the music And a music transmitting means for transmitting music information indicating each of the music extracted by the music extracting means to the karaoke terminal that has transmitted the proposal request that triggered the extraction. I have.

  And the said karaoke terminal transmits the proposal request | requirement for request | requiring the proposal of the music suitable for a specific user to sing to the said server in the state with the identification information allocated to the user. And music proposing means for proposing each of the music indicated by the music information transmitted from the server as music suitable for the user to sing.

  If it is this structure, the score which is the score result of the music among the music concerning the score result when the requesting user according to the proposal request sings the music exists in an area where the score distribution has a predetermined number of samples or more. Each song can be proposed as a song suitable for the user to sing.

  Here, “the music in which the score as the result of scoring of the music among the music related to the scoring result when the requesting user sings the music is in a region where the number of samples in the scoring distribution is equal to or greater than the predetermined number” is the requesting user The result of scoring when singing in the past is a song in a region with a large number of samples in the current scoring distribution.

  For such music, if the number of samples increases to some extent, the scoring results will be improved even slightly from the time of singing in the past, that is, if the score can be increased even slightly, the ranking among multiple users will increase. It can be said that the music can be raised.

  Therefore, if the music as described above is proposed as a music suitable for the user to sing, the user can easily select a music that easily obtains a high rank from the music proposed in this way. You will be able to choose.

  In this configuration, the “suggestion request” transmitted from the karaoke terminal to the server means that when the karaoke terminal is operated to request the proposal of music together with the input of the identification information, the identification information When an operation for requesting a music proposal is performed after logging in, the karaoke terminal transmits the identification information to the server.

  Moreover, the proposal of "the music suitable for a user to sing" by the karaoke terminal mentioned above is the karaoke terminal side in the display mode which can identify each applicable music, for example, such a music. What is necessary is just to implement | achieve by displaying.

  Further, the above-described specification of the scoring distribution by the server may be to selectively specify the corresponding scoring distribution from the scoring distributions stored in the storage unit as a result calculated in advance. It may be calculated each time a request is received.

  In addition, when the above-described scoring distribution is specified by the server, the scoring results collected each time scoring is performed when the user sings may be referred to. In order to collect scoring results in this way, it is conceivable to make the above configuration as a second configuration (claim 2) shown below.

  In the server of this configuration, when the scoring result scored at the time of the user's singing is received from the karaoke terminal, the score as the scoring result is assigned to the music related to the singing and the identification information assigned to the user. Result storage means for associating and storing the result in the storage unit is provided. Then, the distribution specifying means relates to the grading stored in the storage unit as a grading result of each of the plurality of users singing the tune for each song stored in the storage unit in association with the identification information of the requesting user. The scoring distribution for each unit score is specified.

  On the other hand, the karaoke terminal is provided with a result transmitting means for transmitting a scoring result indicating the score scored at the time of the user's singing to the server with identification information assigned to the user.

With this configuration, every time scoring is performed on the karaoke terminal side, the scoring results are collected on the server side, and the scoring distribution can be specified using the scoring results thus collected.
In this configuration, the identification information stored by the result storage means is, for example, input by the karaoke terminal at the time of scoring or logging in and transmitted to the server together with the scoring result.

  By the way, in each composition mentioned above, regardless of the attribute (for example, genre, singer, singing language, tempo, song length, rhythm, etc.) of the song, the music related to the scoring result when the requesting user sings the song. The corresponding music may be proposed from the list. However, the corresponding music may be proposed in advance from the music having the parameter of the attribute desired by the requesting user.

For this purpose, it is conceivable that each of the above-described configurations is as shown in a third configuration (claim 3).
In this configuration, it is assumed that a parameter corresponding to the attribute of the music is assigned to each of a plurality of music, and the server receives a proposal request with identification information and specific parameters from the karaoke terminal. In this case, the distribution specifying means specifies the scoring distribution for each piece of music stored in the storage unit as a scoring result when the requesting user sings the music to which the parameter is assigned.

If it is this structure, it is a music which concerns on the scoring result at the time of a requesting user singing a music, Comprising: From the music of the attribute which the user desires, applicable music can be proposed.
In addition, the above-described scoring distribution specified on the server side is a unit score for each piece of music related to scoring when the requesting user sings a piece of music when the plurality of users sing the piece of music. What is necessary is just to be distributed for every, and the specific content is not specifically limited. For example, it is conceivable to specify a normal distribution of scores related to scoring when a plurality of users sing each song as a scoring distribution.

For this purpose, each of the above-described configurations may be configured as a fourth configuration (claim 4) shown below.
In the server having this configuration, the distribution specifying unit uses the normal distribution N (μ, σ ^ 2) of the scores related to the scores stored in the storage unit as the score results of each of the plurality of users for each song as the score distribution. Specifically, among the music stored in the storage unit as the scoring result when the requesting user sings the music, the music extracting unit specifies the score as the scoring result of the music by the distribution specifying unit. In the normal distribution as the scoring distribution, each piece of music in the ± 2σ region is extracted.

If it is this structure, the normal distribution N ((micro | micron | mu) ^ 2) of the score which concerns on scoring at the time of each of a some user singing for every music can be specified as scoring distribution.
In this configuration, the music extraction means extracts music in the region of ± 2σ in the normal distribution. This is because this region is “a region in which the number of samples exists in the scoring distribution more than a predetermined number”. Because it can be said.

  For example, in the normal distribution, about 68% of the total number of samples exists in the region of ± 1σ, about 96% of the total number of samples exists in the region of ± 2σ, and all samples in the region of ± 3σ. It is known that about 98% of the number is present (for example, paragraph 0010 of JP-A-5-183749). In this statistical value, it can be said that there is almost no difference between the ± 2σ region and the ± 3σ region. Therefore, if each piece of music that becomes the ± 2σ region is extracted, most of the samples are It is sufficient to make the existing area “an area where a predetermined number or more of samples exist in the scoring distribution”.

  Moreover, as a structure for solving the said subject, it is good also as a server provided with all the means with which the server as described in any one of the said 1st structure to the 4th structure is provided. Similarly, it is good also as a karaoke terminal provided with all the means with which the karaoke terminal in any one of the said 1st structure to the 4th structure is provided.

If it is these structures, a part of karaoke system of said each structure can be comprised.
Moreover, in order to solve the said subject, the 1st method (Claim 7) including the following procedures can be considered as a music proposal method.

  In this method, when a proposal request with identification information assigned to a specific user is generated, a user (hereinafter referred to as “requesting user”) identified by the identification information related to the proposal request sang a song. For each piece of music stored in the storage unit as a scoring result at the time, the distribution of the points related to the scoring stored in the storage unit as the scoring result of each of a plurality of users singing the music (hereinafter “scoring distribution”) And the score that is the score result of the music among the music stored in the storage unit as the scoring result when the requesting user sang the music is the distribution specifying procedure for the music. The music extraction procedure for extracting each piece of music in an area where the number of samples is greater than or equal to a predetermined number in the specified scoring distribution, and the music extracted by the music extraction procedure And music proposed procedure proposed as music suitable for singing, are included.

With this method, the same operation and effect as any of the above karaoke systems can be obtained.
This method may be a second method described below.

  This method includes a result storing procedure for storing a score, which is a scoring result scored when a user sings, in a storage unit in association with a song related to the song and identification information assigned to the user. Yes. In the distribution specifying procedure, for each piece of music stored in the storage unit in association with the identification information of the requesting user, the score stored in the storage unit as a scoring result of singing the music by each of a plurality of users. The scoring distribution for each unit score is specified.

With this method, the same operation and effect as the karaoke system in the second configuration can be obtained.
In each of the above methods, when a parameter corresponding to the attribute of the music is assigned to each of the plurality of music, the third method shown below may be used.

  Among these methods, in the distribution specifying procedure, when a request for proposal with identification information and a specific parameter assigned to a specific user is received from the outside, the requesting user selects a song to which the parameter is assigned. The said scoring distribution is specified for every music memorize | stored in the memory | storage part as a scoring result at the time of singing.

With this method, the same operation and effect as the karaoke system in the third configuration can be obtained.
This method may be a fourth method as described below.

  Among these methods, in the distribution specifying means procedure, the normal distribution N (μ, σ ^ 2) of the scores related to the scores stored in the storage unit as the scoring results sung by each of a plurality of users for each music is scored. Specifically, in the music extraction means procedure, among the music stored in the storage unit as the scoring result when the requesting user sang the music, the score as the scoring result of the music is the distribution for the music Each piece of music in the range of ± 2σ in the normal distribution which is the scoring distribution specified in the specific procedure is extracted.

With this method, the same operation and effect as the karaoke system in the fourth configuration can be obtained.
In order to solve the above-mentioned problem, a program for causing a computer system to execute various processing procedures for causing the server in any one of the first to fourth configurations to function as all means Good. Similarly, it is good also as a program for making a computer system perform the various process procedures for functioning as all the means with which the karaoke terminal in any one of the said 1st structure to the 4th structure is provided.

If it is a computer system controlled by this program, a part of the karaoke system in any of the first to fourth configurations can be configured.
The above-described program is composed of an ordered sequence of instructions suitable for processing by a computer system, and is provided to a karaoke system or a user who uses the karaoke system via various recording media or communication lines. Is.

Embodiments of the present invention will be described below with reference to the drawings.
(1) Overall Configuration As shown in FIG. 1, the karaoke system 1 includes a server 10 and a plurality of karaoke terminals 20 that are communicably connected via a network 100.

  The server 10 includes a control unit 12 that controls the operation of the entire server 10, an interface unit 14 for connecting the server 10 to the network 100, a storage unit 16 for storing various information, and the like. In addition, this server 10 is good also as a system comprised by the several computer which each operate | moves in cooperation.

The karaoke terminal 20 stores a control unit 22 for controlling the operation of the karaoke terminal 20 as a whole, an interface unit 24 for connecting the karaoke terminal 20 to the network 100, music data or video data indicating the accompaniment content and lyrics of the performance music. The storage unit 26, the wireless communication unit 28 for controlling the wireless communication with the remote control terminal 40, the display unit 30 for displaying various images, the operation unit 32 including a plurality of key switches, and the sound from the microphone 34. And an audio input / output unit 38 that controls the audio output from the speaker 36.
(2) Processing related to scoring Hereinafter, processing related to scoring (single scoring processing) executed on the karaoke terminal 20 side and processing (result storage processing) executed on the server 10 side due to this processing are shown in FIG. Based on
(2-1) Singing scoring process by karaoke terminal 20 First, the processing procedure of the singing scoring process performed according to the program memorize | stored in the memory which the control part 22 of the karaoke terminal 20 incorporates is demonstrated. This singing scoring process is repeatedly executed after the karaoke terminal 20 is activated.

When this singing scoring process is activated, it is first checked whether or not the scoring function for scoring the singing is enabled based on the operation state of the operation unit 32 (s110).
If it is determined in s110 that the scoring function is not enabled (s110: NO), the singing grading process is immediately terminated.

  On the other hand, if it is determined in s110 that the scoring function is enabled (s110: YES), a standby state is reached until playback of the music based on the voice input / output unit 38 ends (s120: NO). The scoring result based on the voice input from the microphone 34 until the end (that is, the scoring result for the song of the specific music) is calculated as a score (s130). Note that the scoring method and the scoring method as a result of scoring here are well-known methods, and thus detailed description thereof is omitted.

  Next, the user and the music related to the scoring result calculated in s130 are specified (s140). In this embodiment, it is configured to log in to the karaoke terminal 2 with identification information assigned in advance prior to singing the music. In s140, the identification information of the user who is logged in at this time is displayed. By acquiring, the user identified by this identification information is specified as the user related to the scoring result calculated in s130.

Then, after the scoring result calculated in s130 and information indicating the user and music (song number in the present embodiment) specified in s140 are transmitted to the server 10 as scoring information (s150), the book The singing scoring process ends.
(2-2) Result Accumulation Process by Server 10 Next, a process procedure of a result accumulation process executed according to a program stored in a memory built in the control unit 12 of the server 10 will be described. This result accumulation process is activated every time the scoring information transmitted from the karaoke terminal 20 is received.

  When the accumulation process is activated as a result, first, the user table of the user (identification information) in the scoring information that triggered the activation is read out from the user table stored in the storage unit 16 (s210). This “user table” is stored in the storage unit 16 as a data table for each user to which identification information is assigned, and as shown in FIG. Number) and the score as the scoring result are registered in association with each other.

Next, the music and scoring results in the scoring information that triggered the activation are registered in the user table read out in s210 (s220).
Next, among the music distribution information corresponding to each of the songs that can be sung on the karaoke terminal 20 side, music distribution information corresponding to the music in the scoring information that triggered the activation is generated based on the scoring result in the scoring information Or it is updated (s230).

  This “music distribution information” is stored in the storage unit 16 as indicating the distribution for each unit score (hereinafter referred to as “scoring distribution”) as the scoring result sung by each of a plurality of users for each of a plurality of songs. Specifically, each of a plurality of users who have a track record of music corresponding to the music distribution information is tabulated for each score related to the score. As shown in FIG. 4, for example, the score distribution in the music distribution information may be a normal distribution centered on an average scoring result.

  In s230, if the corresponding music distribution information is not stored, it is generated. On the other hand, if the corresponding music distribution information is stored, the activation is performed among the number of users for each score in the music distribution information. The score is updated by adding “+1” to the number of users of the score as the scoring result in the scoring information.

In this way, after s230 is performed, the result accumulation process ends.
(3) Processing related to music selection From here, processing related to music reproduction executed on the karaoke terminal 20 side (music singing processing), and processing executed on the server 10 side due to this processing (recommended proposal processing) Will be described with reference to FIG.
(3-1) Music Singing Process by Karaoke Terminal 20 First, the processing procedure of the music singing process executed by the control unit 22 of the karaoke terminal 20 will be described. This music singing process is activated when an operation for starting music selection is performed by the operation unit 32 (or the remote control terminal 40) after the karaoke terminal 20 is activated.

  When this song singing process is activated, it is first checked whether or not the operation that triggered the activation is an operation for requesting the recommendation of a recommended song (hereinafter referred to as a “suggest request operation”) ( s310).

  In the present embodiment, one or more attributes such as genre, singer name, singing language (lyric language), tempo, song length, rhythm, etc. are defined for each song that can be sung on the karaoke terminal 20 side. As an operation to start the above music selection, a parameter indicating any attribute is specified, and an operation to request a music proposal with the same parameter as that specified can be performed. Has been. In s310, it is determined that a proposal request operation has been performed when such an operation has been performed.

  If it is determined in s310 that the operation is not a proposal request operation (s310: NO), a process (selection process) for allowing the user to arbitrarily select a music from a plurality of music is started (s320). It will be in a standby state until operation for selecting a music is performed (s330: NO). The selection process by s320 is a well-known process for selecting a song, and is not a process that is a characteristic part of the present invention.

  After that, when an operation for actually selecting a song is performed (s330: YES), after the selected song is played back through the voice input / output unit 38 and the speaker 36 (s340). This music song singing process ends.

  On the other hand, if it is determined in s310 that the operation is a request for proposal (s310: YES), the user specified for the operation is specified (s350) and the parameters specified in the operation are specified, as in s140. , And information indicating the user (identification information) thus identified is transmitted to the server 10 as proposal request information (s360).

  From the server 10 that has received the proposal request information, as will be described later, a data table in which whether or not each song scored in the past by the user related to the operation is a recommended song (Yes or No) is registered in association with each other. A music information table (see FIG. 6) is transmitted.

  Thus, after the proposal request information is transmitted, the server 10 waits until the music information table is transmitted from the server 10 (s370: NO). When the music information table is transmitted (s370: YES), it is registered in this table. Each of the songs that have been recommended songs ("Yes" is associated) is extracted (s380).

Next, each piece of music extracted in s380 is displayed as recommended music on the display unit 30 (s390).
Thus, after each recommended music is displayed on the display unit 30, the user can perform an operation of selecting any of these recommended music using the operation unit 32.

  Thus, after each recommended song is displayed on the display unit 30, the process proceeds to s330, and a standby state is entered until an operation for actually selecting a song (recommended song) is performed (s330: NO).

Then, when an operation for actually selecting the music is performed (s330: YES), after the recommended music selected in this way is reproduced through the voice input / output unit 38 and the speaker 36 (s340). ), The song singing process is finished.
(3-2) Recommended Proposal Processing by Server 10 Subsequently, a processing procedure of recommended proposal processing executed by the control unit 12 of the server 10 will be described. This recommendation proposal process is started each time the proposal request information (according to s360) transmitted from the karaoke terminal 20 is received.

  When this recommended proposal processing is activated, first, among the songs that can be sung on the karaoke terminal 20 side, the attributes (and parameters thereof) defined for this song are those in the proposal request information that triggered the activation. Are identified (s410).

  In the present embodiment, an attribute table, which is a data table in which each attribute song is registered in association with each song that can be sung on the karaoke terminal 20 side, is stored in the storage unit 16 (see FIG. 7). For this reason, in this s410, the music whose attribute parameter corresponding to the music matches that in the proposal request information is specified from the music registered in the attribute table.

  Next, a table generation process is performed to generate a music information table, which is a data table registered in association with whether or not each of the music specified in s410 is a recommended music (Yes or No) ( s420) After the music information table generated here is transmitted to the karaoke terminal 20 (s430), the recommended proposal process is terminated.

  Here, the procedure of the proposal table generation process will be described. As shown in FIG. 8, first, a music information table with no data registered is generated (s510). As described above, this music information table is a data table for registering a score of a specific user and whether or not it is a recommended music for each music (see FIG. 6).

Next, out of the music specified in s410, any music that is not a processing target in the subsequent processing is extracted as a target music (s520).
Next, it is checked whether or not the user (hereinafter referred to as “requesting user”) in the proposal request information that triggered the activation of the recommended proposal process has a current performance of the target music (s530). Here, if the target music is registered in the user table of the requesting user among the user tables stored in the storage unit 16, it is determined that there is a scoring record.

  If it is determined that there is a scoring result in s530 (s530: YES), the scoring result in that result is read (s540). Here, the scoring result of the target music in the user table referred to in s530 is read out.

Next, of the music distribution information stored in the storage unit 16, music distribution information corresponding to the current target music is read (s550).
Next, the scoring result read out in s550 is a specific area (score) in which a predetermined number of samples (that is, the number of people) are present as seen from the scoring distribution in the music distribution information read out in s540. It is checked whether it is within the range (s560).

Also, if the requested user's scoring results are in the scoring range where there are many samples, the music related to the scoring is recommended in the sense that the ranking will rise greatly even with a slight change in scoring results, that is, a slight improvement in scoring If the condition that the music is set is set, it is determined that the scoring result read out in s540 is in a specific region when the scoring distribution is in a region where many samples exist. . When the case where the scoring distribution is the normal distribution N (μ, σ ^ 2) is illustrated (see FIG. 4), it can be determined that the scoring distribution is in the specific region by being in the region of ± 2σ. In addition, since the region of ± 2σ in the normal distribution is a region where about 96% of the total number of samples exists, it can be said that it is a region where most of the samples exist statistically.
(In the above, the region of ± 2σ was defined, and it was explained that it was low and high.)
Here, the specific area varies depending on the conditions for the recommended music. For example, if the scoring result of the requesting user is in the lower score range, the music piece related to the scoring is highly likely to increase the scoring result (if you sing a little better, you can easily get a higher rank) If the condition of “Yes” is set, the scoring result read out in s540 is in a specific region when there is only a certain number of samples in the lower scoring range in the scoring distribution. It is determined that there is. When the case where the scoring distribution is the normal distribution N (μ, σ ^ 2) is illustrated (see FIG. 4), it can be determined that the scoring distribution is in the specific area by being in the area smaller than −2σ.

  Contrary to the above, if the requesting user's scoring result is in the higher scoring range, the recommended music in the sense that a higher rank can be obtained if the scoring result according to the scoring result is obtained. If the condition is set, the scoring result read out in s540 is in a region where only a certain number of samples are present in the higher scoring range in the scoring distribution. It is determined that To illustrate the case where the scoring distribution is the normal distribution N (μ, σ ^ 2) (see FIG. 4), it can be determined that the scoring distribution is in the specific area by being in the area larger than + 2σ.

  If it is determined in s560 that the scoring result is in the specific area (s560: YES), the current target music is set as the recommended music, and this target music is read out in s540 performed immediately before. The score information and the value “Yes” indicating that it is a recommended song are registered in the song information table generated in s510 in a state associated with the score (Yes).

  On the other hand, when it is determined in s560 that the scoring result is not in the specific area (s560: NO), the current target music is the scoring result read out in s540 performed immediately before and the recommendation In a state where it is associated with the value “No” indicating that it is not a song, it is registered in the song information table generated in s510 (s580).

  Thus, after registration in the music information table by s570 and s580, or when it is determined that there is no scoring record in s530 (s530: NO), all the music specified in s410 is stored. It is checked whether or not the music has been processed, that is, whether or not the processing for all the music has been completed (s590).

  If the processing for all the music pieces has not been completed in s590 (s590: NO), the process returns to s520, and after the other music piece is selected as the target music piece, the processes after s530 are performed.

Then, when the processing for all the music pieces is completed (s590: YES), the table generation processing is ended, and the process returns to the recommended proposal processing.
(4) Actions and effects If the karaoke system 1 is configured as described above, among the music related to the scoring result when the requesting user according to the proposal request sings the music, the score as the scoring result of the music is scored. Each of the songs in the region where the number of samples is greater than or equal to a predetermined number can be proposed as songs suitable for the user to sing (see FIG. 6).

  Here, “the music in which the score as the result of scoring of the music among the music related to the scoring result when the requesting user sings the music is in a region where the number of samples in the scoring distribution is equal to or greater than the predetermined number” is the requesting user The result of scoring when singing in the past is a song in a region with a large number of samples in the current scoring distribution.

  For such music, if the number of samples increases to some extent, the scoring results will be improved even slightly from the time of singing in the past, that is, if the score can be increased even slightly, the ranking among multiple users will increase. It can be said that the music can be raised.

  For this reason, for example, if a condition is proposed in which music that is in the range of ± 2σ and ± 3σ in the normal distribution is proposed as music suitable for the user to sing, it is proposed to the user. It becomes possible to easily select a song that easily obtains a high ranking from among the selected songs.

  Further, in the above embodiment, every time scoring is performed on the karaoke terminal 20 side, the scoring results are collected on the server 10 side (s150 in FIG. 2), and the corresponding music distribution using the scoring results thus collected. Information can be updated (s230 in FIG. 2) and specified (s540 to s550 in FIG. 8).

  Moreover, in the said embodiment, it is a music which concerns on the scoring result when the request user concerning proposal request information sings a music, Comprising: The music in which the attribute in the proposal request information, ie, the attribute which a request user desires, is specified. Then, the music extracted from the music specified in this way can be proposed as the recommended music (s520 to s580 in FIG. 8).

Moreover, in the said embodiment, the music distribution information which shows the normal distribution N ((micro | micron | mu) ^ 2) of the score concerning the scoring at the time of each of several users singing for every music can be specified (s550 of FIG. 8). ).
(5) Modifications Embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and can take various forms as long as they belong to the technical scope of the present invention. Needless to say.

  For example, in the said embodiment, when the user logs in at the time of singing with the karaoke terminal 2, the identification information at the time of the login is acquired by the karaoke terminal 2 each time. However, it may be input by the operation unit 32 whenever the identification information of the user is required.

Moreover, in the said embodiment, every time the server 10 receives scoring information from the karaoke terminal 20, the music distribution information is updated (s210 to s230 in FIG. 2), and the server 10 requests a proposal from the karaoke terminal 20. Each time it is received, the corresponding music distribution information thus updated is selectively specified (s550 in FIG. 8).
