Export important Sonos data to files, such as your alarms, favorites, radio stations and Sonos playlists.  Works for every Sonos device on your network, both S1 and S2 at the same time, and even deactivated ones (though those must be wired to your network).  Choose a Playlist from an S1 system and play it directly on S2 (or vice versa). (Playing an entire playlist requires the Premium Feature Pack at additional cost).  See all Sonos Rooms and what is playing, plus a simple, clean Now Playing display.  This app is NOT connected to, or endorsed by, Sonos.  See which devices are S1 and S2 compatible to prepare your system for updates.  Those playlists can be imported directly.  Sonos is a registered trademark of Sonos, Inc.
