Custom Widget: Spotify Playlists for Spotify Binding

Hi Gytis,

I have the following items. Placed them into the Widget, like so, but I get an error . Ive created a new String called spotifyTrackPlay, but again, same issue. Tried many things! Would be great if you could put a bit more detailed information in the Readme about how to get this to work as it looks fantastic.

String spotifyToken                                {channel="spotify:player:a54a8a62:accessToken"}
Player spotifyTrackPlayer                                {channel="spotify:player:a54a8a62:trackPlayer"}
