Just a link to the web player. To pin to your chromebook launch bar.
This app basically redirects you to the play.spotify.com domain via Facebook. You need to have linked your Spotify account to Facebook in order to get access to the web player.
This app is in no way affiliated with either Spotify or Facebook. I just wanted to pin the Spotify web player to my Chromebook quick launch bar instead of bookmarking the url. Now I can, and so can you :)
