The digital content store provides users with an opportunity to purchase authorized usage of digital content, such as single or multiple music tracks, video, movies, and/or video games. The users can also buy license to a desired track for a fixed number of times, e.g. preferably the users can listen on three different machines simultaneously. Users can also burn a play list of X number of times, for example ten. The burn limit preferably applies to the play list, not the song. Mixed media capability is provided that allows the purchase of digital content and/or physical media. The digital content store system comprises a unique digital rights management system and a back-end enabling system that controls these digital rights.
