Abstract: Example techniques involve selection of playback devices within a media playback system for outputting a media stream based on user input. An example implementation involves a controller causing a plurality of first representations of at least some of a plurality of playback devices to be displayed on a first portion of a display. The controller causes a plurality of second representations of at least some of one or more groups playback devices to be displayed on a second portion of the display, each group having at least two associated playback devices of the plurality of playback devices. The controller receives an input indicative of a particular group of the one or more groups and adjusts a selected status of the particular group. The controller also determines which playback devices are associated with the particular group, and adjusts a selected status of the playback devices that associated with the particular group.
