I think Inc mentioned a while back that doing something with the soundtrack was already on his list of things to tweak. If/when they get a chance to do that, I'd like to see some kind of Pandora style option where the players can pick their own style of music and have that fed to them (I've always had this -admittedly ultra dorky - idea of plying the lonely skies of the vast universe with music that touches my soul blaring out to endless void.)
So anyways... it might be a way to boost VO revenue too if they could add an option to let players purchase songs they like (maybe with a list of what played during you last couple of sessions so you don't need to do it immediately?)
Would definetely need to be an optional/opt-in thing (I could see it as being a drawback bandwidth wise on a phone.)
They could also enable some really whacky/funny stuff too (like if you lose a formal duel, then you are forced to listen to a song of the winner's choice!)

PS. I've been meaning to suggest this for a while, so if I already have and this is a dupe, please burn/delete this post.
