If you listen to a song on Apple Music, when your playlist stops, if you have infinity ticked, it continues to play artists like that. Sonos is now supporting that. I’ve had the Sonos (latest software) continue playing after an album similar tracks. This is new.
Except the Sonos Mac app doesn’t show it’s still playing, what it’s playing or the ability to stop!!! So you have to tap the speaker (or use the little widget I am using also).
Looks like Apple have unlocked a feature and the Sonos Mac app (don’t know about others) is needing to catch up.
