I use the unsanctioned integration with Elan G on my system every day. It's OK, sometimes a little slow....But it works, is limited, but works reasonably well. It has survived numerous Sonos updates, that has not killed any functionality as far as I can tell. I do Internet radio, SiriusXM, Pandora (rarely), music library, favorites, Playlists and Deezer. I don't use Spotify. Transport controls work well too.

But I frequently use the Sonos app on my iPad too, especially for more robust usage.

I would consider myself a power user. I personally use my Sonos system, every day...and would be pissed if someone stole it. I like to play and listen to music
