  • receiving, at a user interface of a controller, one or more commands to establish a synchrony group comprising at least a first zone player and a second zone player connected via a local area network, wherein, in response to receiving the one or more commands, the controller causes the first zone player and at least the second zone player to form a synchrony group;

    the first zone player and the second zone player joining the synchrony group, wherein in the synchrony group, the first zone player transmits clock timing to at least the second zone player via the local area network, the second zone player determines a timing differential relative to the clock timing, and the first zone player and the second zone player playback audio content items in synchrony with each other based at least in part on audio content, playback timing information that the first zone player streams to at least the second zone player via the local area network, and the clock timing;

    displaying, at the user interface, a list of audio content items for playback in synchrony by the first and second zone players of the synchrony group, wherein (i) at least one of the audio content items on the list is located on a device within the local area network and (ii) at least one other of the audio content items on the list is located on a wide area network, outside of the local area network; and

    transmitting control information from the controller to at least the first zone player, wherein the control information comprises an identification of an audio content item selected from the list of audio content items; and

    the first zone player receiving the control information from the controller, wherein receipt of the control information causes the first zone player to (i) obtain the selected audio content item, (ii) stream the audio content item and playback timing information to at least the second zone player of the synchrony group via the local area network, and (iii) use the clock timing and playback timing information to playback the selected audio content item in synchrony with at least the second zone player.
