Abstract: A digital content distribution and subscription system for digital data files, such as digital audio and video data files, which provides subscribers, for example, with music or video from locally-stored digital files or on demand for a fee. The system may optionally provide streaming digital data as well as locally-stored digital files. After registration onto the system, a subscriber may select from a relatively wide variety of available digital content, for example, music content ripped from a high-quality digital source to provide relatively consistent digital quality to subscribers. In one exemplary implementation, subscribers may subscribe to a predetermined number of songs slots for a period of time, for example, about 200-400 song slots per month. The subscriber may then select songs from various playlists which causes encrypted digital audio files for the selected music to be downloaded to the subscribers's PC.
