I wanted to be able to use my Apple Remote Control to change tracks, but unfortunatley Spotify does not open up the API to accept inputs for changing controls. But there is a solution!
Spotify Mac Remote is a plugin for Spotify that allows you to use your Mac’s remote control to Play, Pause and change tracks.
1) Firstly you need to Install SIMBL2) Secondly download the plugin
3) Extract the the zip file and place the .bundle file in (Macintosh HD /Library/Application Support/SIMBL/Plugins/)
4) Restart Spotify and you should be flying!
