For anyone trying to find classical radio on the web, this is a pretty good resource: http://www.operacast.com/opstations.htm

Wherein, if you scroll down a bit, you'll find a list of stations worldwide that do streaming audio, what kbps rates they stream at, and what players they're geared for, as well as direct links to their audio streams and schedule pages. (Note that this site is opera specific, but where there's opera there's usually everything else too -- including folk music programming, if you look hard enough.) There are also links to Real Audio, et al., for downloading players, and a very useful little article called "Internet Radio for Simpletons", for anyone who finds all this utterly mystifying.

Happy surfing,
