Example implementations may relate to creation and control of channels. In particular, a computing device may receive a first channel-addition request indicating content from a first audio-provider service and may responsively send to a server an instruction to establish a first channel that provides access to content from the first audio-provider service via an application-program account. With this arrangement, a subsequent second channel-addition request may then similarly lead to establishment of a second channel that provides access to content from the second audio-provider service via the application-program account. After channel-additions, the device may determine a first selection of the added first channel and may responsively cause content from the first audio-provider service to be output by an audio output device. Then, the device may determine a second selection of the added second channel and responsively cause content from the second audio-provider service to be output by the audio output device.
