Spotify activity while playing music through Sonos or Alexa?

[user-removed]

Has anyone come up with a workaround to allow Spotify to learn from what I listen to when I listen on Sonos? Have just come back to try Spotify again based on Discover Weekly, but I almost always listen through my Sonos players -- so Spotify is not learning anything about my tastes. I would even accept plugging the laptop directly into a Sonos player if that works?  I'm pretty geeky so can probably implement a more complicated solution...    

Does Spotify learn from what I play via my Amazon Echo?  

Thanks!
