PROBLEM TO BE SOLVED: To provide a Karaoke machine with a scoring function that makes it possible to accurately decide whether an actual singing is good irrelevantly to the difficulty. SOLUTION: A distribution center collects and totals scoring logs of a plurality of Karaoke machines to calculate difficulties by pieces of music. A Karaoke machine scores the frequency of a singing to calculate basic points, calculates similar additional points according to difficulty data, and increases or decreases the additional points according to the basic points. The additional points are added to the basic points to obtain final points. Consequently, while the singing is scored principally based upon the singing frequency, the difficulty is taken into consideration for the scoring to obtain the final scores while the difficulty is taken into consideration.
