An electronic musical instrument A automatically performs a music piece by replaying music piece data. When music piece data stored in an external storage device 36 or music piece data taken in via an interface circuit 51 is stored in an internal storage device 35, filenames of copyrighted music piece data among the above-described music piece data are automatically changed. When music piece data stored in a ROM 33 or the internal storage device 35 is copied into the external storage device 36 or is outputted to the outside via the interface circuit 51, the copy and the output of copyrighted music piece data among the above-described music piece data is prohibited. When an external device 52 requests the electronic musical instrument A to transmit music piece data stored in the internal storage device 35 or the like, filenames of copyrighted music piece data among the above-described music piece data are protected from being displayed on the external device 52. As described above, copyright on music piece data is protected easily and effectively.
