Examples described herein involve expanding playback of a media item from a first playback device to a second playback device. In one example, a first playback device of a first zone, identifies a second playback device within a proximity of the first playback device, determines that the second playback device is playing a media item as part of a second zone, and based on the determination, joins the second zone and begins playing the media item in synchrony with the second playback device. In another example, a first playback device, while playing a media item as part of a first zone, determines that a second playback device of a second zone has entered a proximity of the first playback device, and responsively, causes the second playback device to join the first zone and begin playing the media item in synchrony with the first playback device.
