For those who like Rock'nRoll, two online stations.
Eagle 181.1fm, http://www.181.fm/index.php?p=mp3links , The Eagle is the clasic stuff, and the Rock is the harder selections.
and
Thunder711. http://thunder711.com/playing.html
If you are so inclined there is an application called Streamripper that you can capture the stream into individual mp3's.

Works with Winamp, an excellent player.
