Example techniques involve suggesting an application of a streaming audio service via an application of a media playback system. An example implementation involves a mobile device displaying, via a control application of a media playback system, a library control comprising indicators representing respective media items of a particular streaming audio service. The mobile device receives, via the library control, input data indicating a selection of an indicator representing a particular media item. The mobile device sends instructions to cause a playback device to play back the particular media item. While the playback device is playing back the particular media item, the mobile device displays, via the control application, a control representing an application of the particular streaming audio service. The mobile device receives input data indicating a selection of the control representing the application of the particular streaming audio service and causes the mobile device to download the application.
