Shouldn't use mplayer; should use mpd! That said... It's a good idea, either way. But the mpd version is what I'd work on, were I working on one. (Indeed, it's conceivable I start working on one... but it will be mpd, if so.) Actually, I probably won't, as it just occurred to me that I can toss prev, play/pause, next, and mmpc icons in Personal Launcher.
