Example techniques may involve managing playback of media content by a playback device. In an example implementation, a playback device receives, from a media service provider, a first media item for playback. The playback device identifies one or more user accounts currently interfacing with the playback device. The playback device transmits, to a media system server, a first message indicating (i) the first media item and (ii) the identified one or more user accounts. After transmitting the first message, the playback device receives, from the media system server, a second message indicating that the first media item is not to be played by the playback device. Responsive to the second message, the playback device transmits, to the media service provider, a request for a second media item. The playback device plays the second media item via one or more speakers.
