There is provided herein a system and method for creating and storing encrypted digital media files that are compatible with a base audio work and that provide the artist some degree of control over how the encrypted files are used. The encrypted files will preferably be stored on an audio CD along with conventional/unencrypted audio in such a fashion that the user will be able to immediately play the audio material. Preferably, the encrypted information will include auxiliary audio information such as additional music tracks, remixes of some of the songs, and other materials that allow a user to create remixes. Additionally, the creator of the encrypted material will be able to specify rules that define how the user can use the encrypted information. Preferably, the encrypted information will be created by the artist during the creation of the CD's unprotected audio content.
