Check out GUNRadio
There’s a new Internet radio site getting started from the community of the IRC network I frequent (GlobalGamers.net) - it’s called GUNRadio, a.k.a. Gaming Unlimited Network Radio. Broadcasting is currently not 24/7, but remember it’s just starting. I’m now a DJ on there, too. 
** Winamp is preferred but not required. Several other media players will play these streams. **
