Last week, down in Los Angeles, I heard a new radio station for the first time. As I sat there, thinking I'd never hear it again, it occured to me that they probably stream off the web. Sure enough, 100.3 The Sound, can be found on the net here http://www.thesoundla.com/?nid=25
Right now they have David Bowie on. They play a widely divergent variety, but it's like the FM stations I remember from when I lived down there.
This type of music might not be for you, but if you have a station you like but can't recieve the normal way, you might want to check to see if they stream live over the 'net.
