One or more sub-playlists (530) are used to generate a playlist for a particular user or groups of users. In one embodiment, the sub-playlists (530) are generated at a network operations center or other location remote from the device on which the ultimate playlist (630) is displayed; however, the sub-playlists (530) can be generated locally or on a local network device.
