Abstract: An example first playback device includes programming to perform functions including receiving a first request to associate with a first playback queue that is stored remotely from, and persists unassociated with, any playback device of the media playback system. The functions also include associating with the first playback queue and designating the first playback queue as an active queue of the first playback device. The functions also include receiving a second request to enter into a group with a second playback device that is associated with a second playback queue, entering into the group with the second playback device, associating with the second playback queue, and designating the second playback queue as the active queue of the first playback device. The functions also include receiving a third request to leave the group, and after receiving the third request, de-designating the second playback queue as its active queue.

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: In an example implementation, a first playback device associates with a first playback queue that identifies items for playback by the first playback device. The first playback device receives an instruction to enter a playback group with a second playback device which is associated with a second playback queue that identifies one or more items for playback by the second playback device. The first playback device enters the playback group with the second playback device. The first playback device is configured to play items from the second playback queue in synchrony with the second playback device while in the playback group. The first playback device receives an instruction to leave the playback group and leaves the playback group. Leaving the playback group involves automatically associating the first playback device with a third playback queue that identifies items for playback by the first playback device.

Abstract: An example method includes receiving a first command by a device to group a first playback device with at least a second playback device for synchronous audio playback. In the example method, the group is associated with a first playback queue comprising a list of one or more items for playback by the group. The example method includes, for as long as the playback device is in the group, receiving a second command by the device to remove the first playback device from the group, wherein the first playback device is ungrouped and automatically associated with a second playback queue. In the example method, the second playback queue comprises a list of one or more items for playback by the playback device.
