Activity reset

At least one tangible, non-transitory computer-readable medium comprising program instructions that are executable by at least one processor such that a system is configured to:

• cause, via a communications interface, a first media playback system in a first listening area to operate in a pre-defined first state in which a queue includes a first set of one or more media items, wherein a first playback device of the first media playback system is located in the first listening area and is configured to play back media items from the queue and operate according to a first configuration comprising one or more settings, wherein the first media playback system is associated with a registered account with each of one or more media services;
• after the first media playback system is operated in a second state, receive, via the communications interface from a trigger source external to the first media playback system, a trigger that causes the first media playback system to revert to the pre-defined first state, wherein the trigger is generated when a second playback device associated with an account that is not associated with the first playback device is associated with the first listening area that includes the first media playback system, and wherein operation of the first media playback system in the second state comprises (i) modification of the queue to include a second set of one or more media items that includes at least one media item that is different from the first set of one or more media items, (ii) modification of the first configuration of the first playback device in the first listening area to a second configuration that includes at least one setting that is different from the one or more settings of the first configuration, and (iii) modification of the registered account of at least one of the one or more media services away from an initial state;
• and
• after receipt of the trigger that causes the first media playback system to revert to the pre-defined first state, cause the first media playback system to revert to the pre-defined first state, wherein the program instructions that are executable by the at least one processor such that the system is configured to cause the first media playback system to revert to the pre-defined first state comprise program instructions that are executable by the at least one processor such that the system is configured to:
• responsive to the trigger:
• (a) populate the queue with only the first set of one or more media items, (b) send one or more commands that reset the first playback device to the first configuration, and (c) send one or more messages that cause the registered account of the at least one of the one or more media services to be reset to the initial state.

A method for controlling a plurality of media playback systems in respective listening areas, the plurality of media playback systems comprising a first media playback system comprising a first playback device in a first listening area connected to a first wireless local area network, the method comprising:

• causing, via a communications interface, the first media playback system to operate in a pre-defined first state in which a queue includes a first set of one or more media items, wherein the first playback device is located in the first listening area and is configured to play back media items from the queue and operate according to a first configuration comprising one or more settings, wherein the first media playback system is associated with a registered account with each of one or more media services;
• after the first media playback system is operated in a second state, receiving, via the communications interface from a trigger source external to the first media playback system, a trigger that causes the first media playback system to revert to the pre-defined first state, wherein the trigger is generated when a second playback device associated with an account that is not associated with the first playback device is associated with the first listening area that includes the first media playback system, and wherein operation of the first media playback system in the second state comprises (i) modification of the queue to includes a second set of one or more media items that includes at least one media item that is different from the first set of one or more media items, (ii) modification of the first configuration of the first playback device in the first listening area to a second configuration that includes at least one setting that is different from the one or more settings of the first configuration, and (iii) modification of the registered account of at least one of the one or more media services away from an initial state;
• and
• after receiving the trigger that causes the first media playback system to revert to the pre-defined first state, causing the first media playback system to revert to the pre-defined first state, wherein causing the first media playback system to revert to the pre-defined first state comprises:
• responsive to the trigger:
• (a) populating the queue with only the first set of one or more media items, (b) sending one or more instructions that resets the first playback device to the first configuration, and (c) sending one or more messages that cause the registered account of the at least one of the one or more media services to be reset to the initial state.
