So basically if u install chromium media edition on your rpi and use Spotify web as the music player and run magic mirror on top of it u might be able to use magic mirror with any Spotify control module to contol playback on the web play.
Please someone develop a module for this
Or just guide me with the first step in creating a module for Spotify
Are you sure on this? I installed a week ago Alexa on RPi and I linked my Spotify Premium account but I was not able to reproduce anything from Spotify. I think there is some limitation, maybe Amazon allows you to play Spotify only on Amazon Echo devices or SampleApp inside AVS is limited?
