Abstract: Example techniques related to polices for media playback systems. An example implementation involves a computing system receiving data representing a request to play back first audio tracks on one or more first playback devices of a first media playback system. The first media playback system is associated with a first subscriber to a streaming media service and the first media playback system is physically located in a first commercial establishment. The computing system determines that the first subscriber is associated with one or more first subscriber policies of the streaming media service and sends instructions to play back the first audio tracks on the one or more first playback devices according to the one or more first subscriber policies of the streaming media service.

Abstract: A first example playback device includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the first playback device to perform functions. The functions include generating a mixed audio signal comprising one or more components of a first audio stream and one or more components of a second audio stream; and playing the mixed audio signal, where the one or more components of the second audio stream of the mixed audio signal played by the first playback device are played in synchrony with a second playback device configured to play the second audio stream. An example non-transitory computer-readable medium and an example method, both related to the first example playback device, are also disclosed herein.

Abstract: In response to receiving the playback mode indication, a playback device is caused to operate within a particular playback mode. After initiating operation of the particular playback mode, the playback device accesses a particular set of routines that is associated with the particular playback mode. The particular set of routines are configured to cause the playback device to play back particular media content with a particular user-defined acoustic parameter, and to configure the playback device to advance between one or more routines within the particular set of routines in response to one or more user interface interactions. The playback device receives the one or more user interface interactions at a user interface associated with the playback device. After receiving the one or more user interface interactions, the playback device executes at least one routine selected from the particular set of routines.
