Lurker
A Online Radio or RCherry Player (they look alarmingly alike).
Both feature a browser built-in with all sorts of suggested feeds.
If you want to use the Droid to browse for feeds, Dolphin Browser behaves well but not all feeds will be playable with these players.
I use AOR the most and it has a complete Shoutcast directory inside so you don't have to use a browser. You can also favorite the ones you like. I listen to all sorts of stuff, including scanners, via the Droid and love it.
As a last resort, if you can find the URL used for the feed, you can type it into a player.
Lefty, This has nothing to do with the droid...just wanted to say "Hi". I too am a lefty guitar player....Carvin DC127, Ltd M150, Chandler custom, and a parts guitar...pumping it through my VOX AD50.
