Abstract
Systems and methods are described for, e.g., providing a statutory audio content service on a portable device that complies with the provisions of the Digital Millennium Copyright Act (DMCA). The user can select a playlist subject to DMCA restrictions but cannot access individual items. Content playback, including skipping of content, is restricted to enforce relevant DMCA provisions. Encryption used to implement digital rights management (DRM) may be modified to enforce such content play rules or, alternatively, an additional layer of encryption may be imposed. Limitations on playback are stored along with the playlist structure in a form that is protected against modification. Information logging content playback is maintained in protected form to be uploaded and relayed to the service provider for the purpose of calculating royalty payments.
