    Abstract: In some implementations, a computing device can transfer a playback queue between the computing device and a playback device. For example, the computing device can detect when the computing device is within a threshold distance of a playback device. The computing device can establish a connection to the playback device and receive state information describing the media playback state of the playback device. The computing device can determine the media playback state of the computing device. The computing device can present graphical user interfaces for initiating a transfer of a playback queue between the computing device and the playback device based on the playback state of the devices. The computing device can initiate a transfer of the playback queue in response to user input to one of the graphical user interfaces or automatically based on the context of the computing device.

    Abstract: In some implementations, a computing system can reduce startup delays for presenting remote media items. For example, when a user requests media content from a media service, the computing system can include information about the first media item to be played in the initial startup messages to reduce the number of roundtrips needed between client and server devices to present the first media item. A media item can include an introductory asset. The introductory asset can be a portion of the full media item that can be decrypted with a local key or not encrypted at all so that a media client can receive and start presenting the introductory media asset quickly while the full media item is being processed by the media client. In some implementations, the system can remove leading silence from the media item so that the amount of delay perceived by the user is reduced.

    Abstract: In some implementations, a computing system can be configured so that a first user device can delegate a first user's media account credentials to second user device corresponding to a second user. For example, a playback device may be configured with a the second user's media account credentials for accessing media items through a network media service. A first user may wish to play media items associated with the first user's media account credentials on the playback device. To do so, the first user device can request a device identifier for the playback device, request and obtain a delegate token for the device identifier from the media service, and provide the delegate token along with media item information to the playback device. The playback device can then use the delegate token to request the media item associated with the first user's media access account.
