More specifically, the genre search is performed by appropriately setting the music genre of karaoke music according to attribute information such as the age, gender, birthplace, and singing place of each user. The present invention relates to a system that can easily find a target karaoke piece according to attribute information of a user to be performed.

  As a method of searching for a karaoke song that a user of a karaoke performance device desires to sing, a karaoke song that has been divided into items by a song name, a singer's name, or the like is searched with reference to a table of contents for music search. There has been a method for reserving music by inputting a music reservation number to a karaoke remote control device. However, at present, a method of searching for a karaoke piece that is desired to be sung by using a portable information terminal such as a karaoke remote control device or a smartphone capable of searching for a piece of music based on various search conditions has become common. Yes.

  In a search system using a karaoke remote control device for music search or a portable information terminal, a unique music genre is set in advance for each karaoke song. For example, music genres such as JPOP, Enka, and animation are set for each karaoke music piece, and music search can be performed by designating a desired music genre. In addition, a system has been developed that can manage the user ID of each user in association with attribute information such as the gender and age of each user, and can perform music search using the attribute information. ing.

The number of times the combination of the attribute information of the person and the music genre occurs is 40 times. Similarly, for song B, the user attribute information is the Tohoku region, the music genre designated by the user is “Kyokyoku”, and the music genre preset for the song is “Okinawa folk song”. The number of combinations of the user attribute information and the music genre is 28. Further, for the music B, the user attribute information is the Hokkaido region, the music genre designated by the user is “Kyokyoku”, and the music genre preset for the music is “Okinawa folk song”. The number of times that the combination of the attribute information of the person and the music genre occurs is 29 times.

  For example, when the number of occurrences of the combination of the user attribute information and the music genre as described above reaches a predetermined number, the user attribute information and the designated music genre are set for the music B. A new associated music attribute information management table 270b is created. In the example described above, when the predetermined number of times is set to 30, a music attribute information management table 270b as shown in FIG. 6A is newly created. In the music attribute information management table 270b shown in FIG. 6 (a), for the music B, the country of origin, which is the user's attribute information, indicates the music genre in Okinawa, Kyushu, Shikoku, China, Kinki, Chubu, Tohoku, and Hokkaido. It is folk songs and the music genre is JPOP in Kanto.

  In the above-described example, when the predetermined number of times is set to 25, a music attribute information management table 270b as shown in FIG. 6B is newly created. In the music attribute information management table 270b shown in FIG. 6B, for the music B, the country of origin, which is the user's attribute information, is Okinawa folk music in Okinawa, Kyushu, Shikoku, China, Kinki, and Chubu. In Japan, the music genre is JPOP, and in Tohoku and Hokkaido, the music genre is Kayokyoku.

  The case of the music B can be considered as a singer or group who actually sings the music B, even when a user from Okinawa recognizes the music B as an Okinawan folk song. This is a case where the user is recognized as a JPOP or a popular song by other local users by arranging the music.

  Note that in the music B as well as the music A, the music genre may be associated with the user's home region by combining the age, and in that case, the music attribute in which the music genre is associated with the age for each home region.
