I’d like to be able to play on multiple devices via apps like Spotify.
Currently, the Spotify app allows me to select to stream to only one device. If I want multiple devices I then need to go to the Sonos app and add the other devices there, and the overall experience is pretty clunky.
Having pre-defined groups that are exposed to the Spotify app so that one can stream to a group directly via the Spotify app would be a real improvement.
