I just thought id point this out
it is under last.fm in the marketplace and is free it is a great app in my opinion.
Works good. I've made it my primary online radio because it is on the xbox360 and the Droid. Nice to have one program that will work wherever I am.
You are right to be wary. There is much bullcrap. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic. - Mark Rippetoe
Not to mention that is "scrobbles" the music you play from your default media player and uploads your preferences to your last.fm account making it even more useful.
