Abstract: Systems, methods, and articles of manufacture to manage tracks and/or other multimedia items are disclosed. An example method includes displaying on an interface of a computing device, a plurality of tracks in a sequential order. The example method receiving, via the interface, an input to play a particular track from the plurality of tracks, wherein the particular track is at a particular position in the sequential order. The example method displaying on the interface, a queue comprising at least a subset of the plurality of tracks to be played after playback of the particular track, wherein each track in the subset of the plurality of tracks is at a different position in the sequential order than the particular position of the particular track.

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receiving an error message indicating that the queue identification indicated in the queue update message has been superseded by a queue identification that indicates a second version of the playback queue at the playback device.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. In some cases, a user modifying the playlist or playback queue may be prompted upon making the modifications whether to also apply the modification to the playback queue or playlist, respectively.

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: 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: Techniques for managing a playlist in a multimedia system are disclosed. According to one aspect of the techniques, the playlist is structured to be able to include as many items as desired. To facilitate the manageability of such playlist, the playlist is built with a plurality of items. Each of the items is associated with metadata that includes information related to, for example, artist, album, genre, composer, and track number. The metadata for each item may be parsed, updated or logically operated upon to facilitate the management of the playlist. In another embodiment, each of the items is either a single item or a group item. A single item contains metadata of a corresponding source. A group item contains metadata of accessing other constituent items, which again may be single items or group items. As a result, the playlist can accommodate as many items as desired in a limited memory space without compromising the manageability of the playlist.

Abstract: A client/server system for authoring an on-line service uses a server machine accessed a client machine which performs authoring operations on information stored on the server machine comprising the on-line service. Requests for authoring operations to be performed on information on the server machine, for authoring the online service, are translated on the client machine into at least one message which is sent to the server machine. The server machine receives the at least one message from the client machine and performs authoring operations identified in the received at least one message so as to author the online service. This information on the server machine is then made accessible by the server machine to other client systems that can be used to access the information without modifying the information, such as a browser.
