US Patent 9361371 Playlist update in a media playback system

Embodiments are provided for updating a playlist that has been added to a playback queue in response to changes to the playback queue. The playback queue may be associated with a zone of a network media system such that items in the playback queue are to be rendered by the zone. The playlist may include one or more items playable by the zone, and may be stored separately from where the playback queue is maintained. Embodiments are also provided for updating a playback queue in response to modifications to a playlist included in the playback queue. In some cases, a user modifying the playlist or playback queue may be prompted upon making the modifications whether to also apply the modification to the playback queue or playlist, respectively.
