To prevent a trouble related to reservation of a musical piece to be played, which is apt to occur when enjoying karaoke in an environment such as a banquet in which many participants are present in a large room, and it cannot be found by whom and when the reservation is performed.

When face image data of a person who made a reservation is matched to face image data of a singer (S235: YES), karaoke play is continued (S240). When the face image data of the person who made the reservation is not matched with the face image data of the singer (S235: NO), reservation information of the singer is searched and registered at the top of a reservation table (S245 and S250), and karaoke play is newly started (S255 and S266). When this karaoke play is completed, a musical piece to be played which is reserved by a participant who should sing is successively karaoke-played.
