Mediaset generation system
Disclosed are various embodiments of systems and methods for generating composite mediasets from mediasets, each comprising media items, associated with a plurality of users. In some embodiments, individual and/or group recommendations are provided for creating a group playlist by aggregating user taste data for a plurality of users in a group. In other embodiments, systems and methods are provided which allow for sharing and playing of a group playlist by users in a group, each of which has a media playback device. Each media item, such as a song, is played from one of the individual user devices for the benefit of all users in the vicinity at the time. Music thus can be “shared” without transferring files potentially in violation of copyrights.
