Sonos app and Spotify issues makes sonos app sucks.
When I do a song search while on the Sonos app with Spotify, I will get only a few results and most of the time not the song I am looking for. When I do the same search directly on the Spotify app, I always get many more options and actually will find the exact song. This is the reason I am saying Sonos App SUCKS. After paying big price for the Sonos device, in my mind, this situation should not be happening. (And please do not respond you need to subscribe to Sonos Radio...)
