After being announced back in late August and being in a public beta for a month, it’s time for Sonos to get an update to control music from the Spotify app.  You won’t need to access  the Sonos app at all when using this.  

This pretty much turns your Sonos speaker into a Spotify Connect speaker.  Also, w/ the ability to designate the music for a multi-room setup.  Overall, making for those who use both, a much-better experience.  It will be available for users w/ a premium subscription.  Spotify users will also be able to take advantage of it on both mobile & desktop apps.
