Abstract: A service for streaming digital audio files to subscribing consumers is provided in a manner compliant with all applicable licenses. A method of using such service may include downloading licensed audio files onto a server configured to be managed automatically to ensure compliance, employing a playlist algorithm associated with the server that is configured to monitor and record certain attributes about the digital audio files, including the performing rights organization, the composer of the audio files, and/or the identify of the copyright owner of the audio file, and tracking the frequency of regeneration of the audio files on the server. An algorithm may be employed that constrains the streaming of the audio files so that consumers may influence the music that is streamed to them pursuant to consumer subscriptions, but limits the direct control over the specific audio files streamed to the subscribing consumers.
