Listening to music on your Windows Phone and use a Last.fm account? You'll need this app installed. ScrobbleMe is a simple app by Arnold Vink, the creator of ZuseMe and ZenseMe, which offers "scrobbling" support for all music played on the Windows Phone ("scrobbling" is basically to feed Last.fm data on your music history). Really handy if you're one to enjoy keeping on top of play counts and show friends what you're listening to. And, it works pretty well.
