A quick internet search will offer many suggestions. Some may require streaming service subscription to access.  

Amazon has a lot if you have it and the upgrade, (called commercial free) that enables the enhanced audio offerings.

Well worth it for the audio alone, no commercials on some TV streams is nice but nit why I rook it.

I'm seeing this on my firestick Amazon Music App account but it should work for non-surround 300s from the Sonos App too. Hoping my 300s show up soon.
