Abstract: A first client device is associated with a first user hosting a shared playback session. While a first media content item from the shared playback session is being presented on a set of presentation devices, the first client device communicates with a set of observer devices for the shared playback session. The first client device receives a request to modify playback of the shared playback session from a second client device, the second client device being one observer device of the set of observer devices. In response to the request to modify playback of the shared playback session, the first client device determines an action to take with respect to the shared playback session. In response to determining the action to take with respect to the shared playback session, the first client device sends a command for the action to each of the set of presentation devices.

Abstract: An electronic device receives a request, from a first device of a host user, to initiate a first shared playback session for the first device and one or more additional devices. The electronic device streams media content from a first playback queue to the first device and to the one or more additional devices, the first playback queue including one or more media content items corresponding to the first shared playback session. The electronic device determines that the first device of the host user has left the first shared playback session and, in response, maintains the first playback queue to be accessed by the one or more additional devices. After the host user has left the first shared playback session, the electronic device provides one or more media content items from the first playback queue to at least one of the one or more additional devices.

Abstract: An electronic device stores, for a first user of a media-providing service, a listening history corresponding to media content items provided by the media-providing service that have been previously consumed by the first user. The electronic device provides a shared playback queue to a first device of the first user and a second device of a second user. The electronic device identifies a source of a first media content item of the one or more media content items in the shared playback queue. Based on the identified source of the first media content item in the shared playback queue, the electronic device determines whether to include the first media content item in the listening history of the first user. The electronic device provides information for a second media content item to the first device of the first user based on the listening history of the first user.
