Implementation is simple and intuitive. From the Pandora app send any station or song or album to any Sonos speaker group in your environment, volume control, and can change groups. More advanced features you must enter the Sonos, but it's more than enough from within Pandora. Flip-side is that everything is available from within Sonos now as well.
It's just what I've been hoping for all these past months. Great implementation impressions from my first glances.
See ya later Spotify and Deezer.
