In order to prevent overwriting your existing Sonos queue, Yonomi appends your Favorite to the queue. Any time you run a 'Play Favorite' action for a Sonos Player, if it is a song, album or playlist it will be appended to the queue and begin playing. The original Sonos queue will remain intact to prevent any third party, such as Yonomi, from overwriting unsaved curated track lists.
There is an exception when playback of a radio station occurs. The radio station plays from the cloud provider and the queue remains entirely unchanged. In this scenario, a station cannot be shuffled, repeated or skipped to a previous track.
