System and method for managing content delivered to a user over a network
A system is provided for managing the delivery of content over a network, particularly songs or music over the Internet. A station and playlist module manages the content delivered by a number of stations over the network, the type of content that may be delivered by each of the stations being specified by a playlist for that station. Preferably, at least one station includes two or more playlists and only one of those playlists specifies the content that may be delivered by that station at any one time. A database that stores information describing the content or songs that stations can deliver may be searched by users who may also request new content when a particular song is not found. Also, preferably there are at least two categories of system users including a first user category having full access privileges and a second user category having less than full access privileges but having access privileges to create and edit at least one station playlist.
