Wondering who you are referring to? But, "why not just use the on-screen controls?" If the phone is on your hip in a clip or in your pocket its much easier to just push the volume key when running or working out verses taking the phone out - waking it up - the pushing the skip song button. If your don't have anything good to add to the thread beat it. Son.
BTW Saschb2b its tied to the framework only works on cm with music mod
