Characteristic amounts are calculated from each of multiple musical piece contents, and then time points when the characteristic amounts exceed a threshold are detected as cut points. Information on the cut point concerning each of the multiple musical piece contents is stored. Based on the stored information on the cut point, a judgment is made as to whether the multiple musical piece contents match each other.
