What about the equalizer, any ideas?
And I forgot one of the most important questions: is it possible in a way to skip music-tracks with the volume keys? Any programm, mod etc to do that? It has been one of my most-used features on android, and I really hope there is a possibility on WP7, too?
Double press the play/pause button on your headphones to skip to the next track and quadruple press to restart the current song. Don't try it as fast as you can though.
