Comment 15 for bug 1437483

The music app transitioned to using "background playlists" a while back, which allows for the system to control the playback/next/previous etc. So all that is left is for the system side, media-hub and bluez, to be linked so that when a bluetooth headset button is pressed it instructs media-hub to perform the action. The tracking of this particular feature is now in bug 1398193, therefore I am marking this bug as a duplicate.
