Abstract: An example implementation may involve a computing system receiving, from a media playback system over the network interface, a request to initiate playback of the particular cloud queue at a first media item. The computing system assigns a playhead pointer to a position within the particular cloud queue that corresponds to the first media item and transmits, to the media playback system over the network interface, an instruction that causes one or more playback devices of the media playback system to initiate playback of the particular cloud queue at the first media item. While the one or more playback devices play back the particular cloud queue, the computing system updates the assigned position of the playhead pointer to indicate the currently playing media item of the particular cloud queue.

Abstract: A connected state is re-established between a mobile device and a playback device based on a previously established connected state with the mobile device. A message may be received via the playback device which comprises a modification to a playlist made before re-establishing the connected state with the mobile device. One or more queued media items in a playback queue may be modified based on the modification to the playlist. The playback device, for example, may then play from the modified playback queue.

Abstract: Based on a credential, an access level of a playback queue for a first control interface and a first subset and second subset of media items in the playback queue may be determined. Media items in the playback queue that were added via a second control interface may be included in the first subset. Media items that were added via a control interface different from the second control interface may be included in a second subset. Information may be provided which identifies the first subset of the media items in the playback queue and the second subset of the media items in the playback queue.

Abstract: Example techniques relate to a playback device that facilitates queue identification. In an example implementation, a playback device stores an association between a playback queue and a first application identifier. After storing the association between the playback queue and the first application identifier, the playback device receives, from a first computing device, a first message comprising a second application identifier. The playback device determines that the second application identifier corresponds to the first application identifier, and responsive to determining that the second application identifier corresponds to the first application identifier, transmits, to the first computing device, a queue identifier associated with the playback queue.

Abstract: Embodiments described herein include systems and methods for providing a social interface for sharing media experience information between households in a community. Users of different households may form the community. The social interface may be provided as an application on a mobile device or an Internet webpage as a portal to the community. The social interface may display a list of households, and a user of the interface may select a household from the list to view information on media being experienced within the household. The selected household may include separate groups of media players configured to render media in synchrony, and the social interface may display, upon selection of the household, a list of the separate groups included in the selected household. The user may then select a group from the list, among other actions, view information on media being rendered by the media players in the selected group.

Abstract: Method and systems are provided for identification of device groups in a network. In an example implementation, a first playback device receives, from a second playback device, first data indicating a first group identification corresponding to a zone group, the zone group including the first playback device and the second playback device, and the second playback device operating as a group coordinator of the zone group. After receiving the first data, the first playback device receives a message indicating that the second playback device is leaving the zone group. In response to receiving the message, the first playback device determines a second group identification corresponding to the zone group and after determining the second group identification, transmits, over to at least one controller device configured to control at least the first playback device and the second playback device, second data indicating the second group identification.

Abstract: Embodiments are discussed for providing private playback queues in a media playback system such that users without access rights to the playback queue may not access the contents of the playback queue. The embodiments may involve receiving at a playback device of a network media system a playlist responsive to an instruction via a first controller interface, adding the playlist to a playback queue associated with the zone, receiving a request from a second controller interface for the information identifying the one or more items in the playback queue, determining that the second controller interface lacks a credential to receive the information identifying the one or more items in the playback queue, and providing the information identifying a subset of the one or more items in the playback queue to the second controller interface.

Abstract: Embodiments described herein may involve inconsistent queues. An example implementation may involve sending, to a playback device of a media playback system, a queue update message indicating a queue identification that indicates a first version of a playback queue at the playback device, and a playlist at the computing device. Thereafter, the implementation may involve receiving an error message indicating that the queue identification indicated in the queue update message has been superseded by a queue identification that indicates a second version of the playback queue at the playback device. Based on the received error message, the implementation may involve determining that the playlist at the computing device is different from the playback queue of the playback device. Based on the determination, the implementation may involve causing second one or more media items in the playback queue to be replaced with first one or more media items in the playlist.

Abstract: Embodiments are provided for updating a playlist that has been added to a playback queue in response to changes to the playback queue. The playback queue may be associated with a zone of a network media system such that items in the playback queue are to be rendered by the zone. The playlist may include one or more items playable by the zone, and may be stored separately from where the playback queue is maintained. Embodiments are also provided for updating a playback queue in response to modifications to a playlist included in the playback queue.

Abstract: An example implementation involves a device of a media playback system transmitting, to a computing system, a request to access a first cloud queue. After transmitting the request, the device receives an indication of first media items in the first cloud queue and an indication of first playback policies that authorize first playback operations on the first cloud queue. While the first cloud queue is accessed, the device displays a control interface with playback controls corresponding to the first playback operations. The device transmits a request to access a second cloud queue. After transmitting the request, the device receives an indication of second media items in the second cloud queue and an indication of second playback policies that authorize second playback operations on the second cloud queue. While the second cloud queue is accessed, the control device displays the control interface with playback controls corresponding to the second playback operations.

Abstract: An example implementation may involve a computing system receiving, from a media playback system over the network interface, a request to initiate playback of the particular cloud queue at a first media item. The computing system assigns a playhead pointer to a position within the particular cloud queue that corresponds to the first media item and transmits, to the media playback system over the network interface, an instruction that causes one or more playback devices of the media playback system to initiate playback of the particular cloud queue at the first media item. While the one or more playback devices play back the particular cloud queue, the computing system updates the assigned position of the playhead pointer to indicate the currently playing media item of the particular cloud queue.

In one example, a media playback system may be configured to (i) receive from the computing device an authorization code that corresponds to a media application installed on the computing device that is authorized to access media from a media service, (ii) transmit to the media service an authorization request with the authorization code, (iii) receive from the media service an authorization token that facilitates obtaining media from the media service, and (iv) transmit to the media service a request for media for playback by the media playback system, where the request for media includes the authorization token.

Abstract: Method and systems are provided for identification of device groups in a network. A playback device in a media playback system may send to a controller device, a transmission indicating a group identification associated with the playback device. The transmission may be sent in response to a request from the controller device for group identification information or a change in a group configuration of the playback device. The controller device may maintain a table of playback devices in the media playback system. The controller device may modify the table based on the transmission received from the playback device.

Abstract: An example implementation may involve removing, by a computing device, a given media item from a queue of media items. The example implementation may further involve adding to the queue an indication that the given media item has been removed from the queue. After adding to the queue the indication, the implementation may also involve receiving, via a network interface, one or more requests for one or more media items from the queue of media items. After receiving the one or more requests, the implementation may involve determining that the computing system has received more than a threshold number of requests for one or more media items since adding to the queue the indication. After determining that the computing system has received more than the threshold number of requests, the implementation may involve removing the indication from the queue.
