Use the skipToPreviousTrack command in the playback namespace to skip to the previous track.
Not all audio sources allow multiple tracks. For example, when a group is streaming an Internet radio station, there is no previous track to skip to. If you send a skipToPreviousTrack command when the audio source does not support multiple tracks, your app will receive an ERROR_PLAYBACK_FAILED, but audio will continue playing.

Request Parameters
There are no request parameters in the body, all of the request parameters are in the header.
This command requires a groupId to determine the target of the command. See the Control documentation for details.
Response
Returns an empty body with a success value of true and generates a metadataStatus event if successful. If your app is subscribed to the playbackMetadata namespace, it will receive this notification.
In the event of a failure, returns a playbackError or a globalError.
For example, if there’s no audio source loaded on the group, or if the audio source loaded does not have a previous track, then your app will receive an ERROR_PLAYBACK_FAILED.
If the player is at the beginning of the queue, your app will get an ERROR_PLAYBACK_NO_CONTENT playbackError.
