Zone Group Control

Example techniques relate to a loss of control of a playback queue. An example implementation involves a playback device receiving, from a native controller, an instruction to add audio tracks to a queue, where, in a first mode associated with the native controller, the playback device is configured to play back from the queue. While the audio tracks are in the queue, the playback device receives, from a media player application associated with a particular wireless protocol, an instruction to play back a media item. In response, the playback device is configured to play back in a second mode associated with the particular wireless protocol, where, in the second mode, the queue is not in use. While playing back the media item, the playback device detects a loss of control by the media player application and configures the playback device to play back in the first mode.
