Savant's Sonos interface is designed to give you fast access to your favorite music. To that end, it's important that you take the time to properly set up your Sonos account.
Using the Savant Remote or the Savant App, you are able to access Sonos playlists, Sonos favorites, and your most recently played songs. To manage your playlists and favorites, or to create new ones, you’ll still need to use your Sonos App.
Please note that Savant is not designed to replace your Sonos experience, it’s meant to enhance it. Just as you can’t access all features of your iTunes account in Sonos, the same holds true for Sonos and Savant.
