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, wherein the group coordinator of a zone group is configured to, when instructed by a controller device, coordinate synchronous playback of media content by one or more playback devices of the zone group; and a first display name for the particular zone group; storing, by the controller device, 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; after receiving the first transmission, receiving, by the controller device, a second transmission from a second 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; 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. 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, wherein the group coordinator of a zone group is configured to, when instructed by a controller device, coordinate synchronous playback of media content by one or more playback devices of the zone group; and a first display name for the particular zone group; 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, wherein the group coordinator of a zone group is configured to, when instructed by a controller device, coordinate synchronous playback of media content by one or more playback devices of the zone group; and a first display name for the particular zone group; storing, by the controller device, 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; after receiving the first transmission, receiving, by the controller device, a second transmission from a second 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 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; 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.
