A method comprising: receiving, by a controller device from a first playback device that is a group coordinator configured for coordinating synchronous playback of media content by a particular zone group of a media playback system, a first transmission indicating: a group identification corresponding to the particular zone group in the media playback system, the particular zone group including the first playback device and at least one additional playback device; that the first playback device is the group coordinator of the particular zone group; and a first display name for the particular zone group; storing, by the controller device, data in a table or a database, the data indicating that the first playback device is the group coordinator of the particular zone group and associating the group identification, the first playback device, and the first display name; causing, by the controller device, a controller interface to display a representation of the first display name of the particular zone group according to the group identification, wherein the representation indicates the first playback device is part of the particular zone group; associating a playback queue with the particular zone group; sending, by the control device, audio playback control commands for the particular zone group to the first playback device; after receiving the first transmission, receiving, by the controller device, a second transmission from a second playback device and a third transmission from the first playback device, the second transmission indicating: the group identification; that the second playback device is the group coordinator of the particular zone group; and an updated first display name of the particular zone group; the third transmission indicating that the first playback device is no longer part of the particular zone group; modifying, by the controller device, the data to indicate that the second playback device is the group coordinator of the particular zone group and to associate the group identification, the updated first display name and the second playback device; updating the controller interface to display a representation of the updated first display name; and after the modifying and updating, sending, by the control device, audio playback control commands for the particular zone group to the second playback device. receiving, by a controller device from a first playback device that is a group coordinator configured for coordinating synchronous playback of media content by a particular zone group of a media playback system, a first transmission indicating: a group identification corresponding to the particular zone group in the media playback system, the particular zone group including the first playback device and at least one additional playback device;
