摘要：
A CD on which only music information specified by the CD-DA is recorded, or a CD on which both music information specified by the CD-DA and music information to be recorded on a CD-ROM are recorded is mounted upon an information processing terminal (10). When the CD on which only music information specified by the CD-DA is recorded is mounted, the information processing terminal (10) acquires, from a directory server (20), an ISRC number that identifies the music information recorded on the CD, and distribution server location information that identifies a content distribution server. The information processing terminal (10) acquires content that is the music information compressed according to the MP3 and encrypted, from the content distribution server identified by the acquired distribution server location information, and the decryption key. The information processing terminal then decrypts the acquired content using the acquired decryption key and reproduces music.
