Abstract: In an example implementation, a system groups a first playback device and a second playback device into first player group. The system associates the first player group with a first playback queue that includes items for playback by the first player group. The first and second playback devices are configured to play items from the first playback queue while in the first player group. The system associates a third playback device with a second playback queue that includes items for playback by the second playback device. Thereafter, the system groups the first, second and third playback devices to form a second player group such that each of the first, second, and third playback devices are configured to play items from the second playback queue. The system removes the first playback device from the second player group and automatically associates the first playback device with the first playback queue.

Abstract: Example techniques involve control of playback queues of a zone-based media playback system. Each zone of the media playback system may play back audio tracks from a respective queue. A control device may display a playback controller that includes multiple control interfaces to control audio playback by the one or more playback zones. When a first playback zone is being controlled, the playback controller may instruct one or more first playback devices of a first zone to play back audio tracks of a queue of the first playback zone. Example implementations may facilitate adding audio tracks to the queue.
