Abstract: Methods and systems provide for coordinated control between multiple devices of playback of a media track or playlist. The multiple devices may form an ad-hoc network for sharing control of media. A control device may coordinate control of the playlist and facilitate playback of the media at a playback device. Then when the control device leaves the group, a second device in the group will seamlessly become the control device and control playback and playlist coordination. The playback device may also be the control device. The playback advice may be a network-enabled speaker. Where the playback device is separate from the control device, the playback device may maintain sufficient information to operate without a control device until a new control device is selected.
