Shoutcast or other streaming radio?
 

Wondering what others are using for listening to streaming radio?

I know Yahoo messenger has LAUNCHcast which gives you access to about 5 free stations, but the rest are pay. And then XM has an internet module, but that's pay as well.

Shoutcast has a good collection of free feeds, but I'm sure there are others I just haven't come across. Any suggestions?
