Abstract

Example implementations involve cloud queue synchronization. An example implementation may involve a playback device sending a request for a window of media items from a cloud queue of media items that is accessible to the playback device via a wide area network, the request including (i) an indication of a reference media item, (ii) a first parameter indicating a number of media items preceding the reference media item to include in the window and (iii) a second parameter indicating a number of media items subsequent to the reference media item to include in the window. The playback device receives, in response to the request for the window of media items, an indication of a particular window of media items from the cloud queue of media items and incorporates the media items of the particular window into a local queue of media items.
