I have a Spotify account and Alexa used to play music from it in my R1S. Alexa suddenly stopped playing music from Spotify, though, and keeps trying to set up a Prime music account. Alexa also says I can set it up to play from Spotify in the app (which it is), but Alexa still isn't using...
I just bought a used R1S and love it. You can get a $10-15K discount as soon as it drives off of the lot (some even with less than 1000 miles), so I couldn’t justify the extra spend for a new one, even though I was off of the waitlist and free to buy new.
