Free for only 3000 downloads. Shoutcast and Icecast only at the moment but the developer says wma to follow. I haven't used it much (because no wma = no BBC) but UI looks good and the promise of low battery drain is pretty attractive.
If you know the URL of a compatible feed you can add it: Favorites > Edit > +I got the app and it's pretty cool and all, but how exactly do you ADD radio stations that aren't in the icecast or shoutcast directories? For example here in Chicago, I want to add ESPN AM1000 WMVP as well as WSCR 670 AM "The Score.".
