I currently use Spotify, but I understand there isn't a Spotify Watch app. I listen to Spotify at home through Alexa. I've wanted to buy an Apple Watch for running, so I can stream music without an iPhone. But I understand that the only way to stream music is with Apple Music. Is there a solution that lets me stream music to my watch, and also to Alexa? I don't want to have to subscribe to two separate music streaming services just so I can listen on Alexa and the Watch. I'd appreciate any advice.
