Have you used Spotify on Amazon echos? A travesty. Every song I requested was a bad cover or obscure version. We had problems getting them to play Beatle songs and Frozen sound track! Repeatedly. We switched back to Apple Music, and the voice commands worked fine. So clearly Apple Music integration was far superior to Spotify at least with Amazon. I read others had this problem, any idea what it was?
