Indicating an association between a social-media account and a media playback system

A tangible, non-transitory computer-readable medium storing instructions that when executed by one or more processors cause a social-media computing system to perform operations comprising:

• receiving, from a first computing device via a network interface, a first message indicating that a first media playback system corresponds to a first social-media account, wherein the first media playback system comprises a first playback device configured to play media content in a zone, and wherein the first computing device is distinct from the first playback device;
• receiving, from the first media playback system, a second message indicating that the first media playback system is currently playing particular media content in the zone;
• and
• in response to receiving the second message from the first media playback system, sending a third message causing a second computing device to display an indication that the first media playback system is currently playing the particular media content in the zone, wherein the second computing device is associated with a second social-media account that is subscribed to the first media playback system, wherein the second social-media account is associated with media content preferences, and wherein the media content preferences indicate a positive preference for the particular media content;
• determining, via the social-media computing system, the second social-media account is associated with the media content preferences;
• and
• in response to determining the second social-media account is associated with the media content preferences, causing at least a second playback device of a second media playback system associated with the second social-media account to play the particular media content while the first media playback system is playing the particular media content.

A method of operating a social-media computing system, the method comprising:

• receiving, from a first computing device via a network interface, a first message indicating that a first media playback system corresponds to a first social-media account, wherein the first media playback system comprises a first playback device configured to play media content in a zone, and wherein the first computing device is distinct from the first playback device;
• determining, via the social-media computing system, a subscription status of a second social-media account with respect to the first media playback system, wherein the second social-media account is associated with media content preferences;
• receiving, from the first media playback system, a second message indicating that the first media playback system is currently playing particular media content in the zone, wherein the media content preferences indicate a positive preference for the particular media content;
• and
• in response to determining the subscription status of the second social-media account and to receiving the second message from the first media playback system, sending a third message causing a second computing device associated with the second social-media account to display an indication that the first media playback system is currently playing the particular media content in the zone;
• determining, via the social-media computing system, the second social-media account is associated with the media content preferences;
• and
• in response to determining the second social-media account is associated with the media content preferences, causing at least a second playback device of a second media playback system associated with the second social-media account to play the particular media content while the first media playback system is playing the particular media content.
