I've successfully connected my Sennheiser MM400 bluetooth headset, and it's playing everything over them. Now I'm using spotify to listen to music, and I tought it would be nice to control spotify via the controls on the right side of the headset.

Anyone got an idea how I could make the controls work?
Thanks!
