Therefore, it is effective to recommend appropriate music to maintain the atmosphere of the place.

  Furthermore, when a specific participant makes a performance reservation, it may be configured as described in claim 3 in consideration of a situation in which a non-specific participant has made a performance reservation before that time. That is, when a performance reservation is made by a specific participant and the music reserved by the non-specific participant before that is in a state of waiting for performance, the extraction means The identification information of the music corresponding to the scoring range based on the scoring result of the specific participant is extracted from the list. Based on the identification information extracted by the extraction means, the creation means recommends that non-specific participants corresponding to the singing history information from which the identification information is extracted change the music currently reserved for performance. Create change recommendation information. The presenting means presents information recommending to change the currently reserved music piece in association with the target non-specific participant based on the change recommendation information created by the creating means. In this way, even if a non-specific participant makes a performance reservation without considering the score range of the specific participant before the performance reservation by the specific participant is made, the non-specific participation The reservation contents of the person can be changed.

  In addition, as information to be presented when the reservation content of the non-specific participant is changed, it can be considered as described in claim 4. In other words, the creating means creates a change recommendation of content that recommends changing the music currently reserved for performance by selecting from the music corresponding to the extracted identification information. The presenting means selects information for changing the currently reserved musical piece from the music corresponding to the extracted identification information based on the change recommendation information created by the creating means. Present in association with a specific participant. By doing in this way, the reservation content of the non-specific participant made before the specific participant can be changed into the content which considered the scoring range of the specific participant.

  By the way, as a method for determining a specific participant from a group of participants, it is conceivable to make it as described in claim 5. That is, the determination unit displays a list image representing a list of logged-in participants on a predetermined display unit on the condition that an operation input instructing the participant to designate a specific participant is received. Then, the participant designated by the participant from the displayed list image is determined as the specific participant. By doing in this way, a specific participant can be determined reliably according to a participant's intention.
