PROBLEM TO BE SOLVED: To provide a Karaoke system and a central device by which singing is mutually evaluated by those who attend Karaoke singing, and which display a recommendation song with ranking based on the singing evaluation. SOLUTION: Singing is mutually evaluated by those who attend Karaoke singing after Karaoke singing is finished, and singing evaluation data obtained by the evaluation are recorded. Later at a Karaoke time, based on the recorded singing evaluation data, highly evaluated song is displayed with ranking as the recommendation song. At that time, the singing evaluation data are extracted by classifying them into the singing evaluation data which are evaluated by a person who presently sits together, and the singing evaluation data which are evaluated by a person who does not presently sit together, and the recommendation song is presented to a Karaoke user.
