Abstract

Embodiments are discussed for providing private playback queues in a media playback system such that users without access rights to the playback queue may not access the contents of the playback queue. The embodiments may involve receiving at a playback device of a network media system a playlist responsive to an instruction via a first controller interface, adding the playlist to a playback queue associated with the zone, receiving a request from a second controller interface for the information identifying the one or more items in the playback queue, determining that the second controller interface lacks a credential to receive the information identifying the one or more items in the playback queue, and providing the information identifying a subset of the one or more items in the playback queue to the second controller interface.
