Here's a site some of you might find interesting: http://www.pandora.com

Just enter the names of your favorite artists, and the site will match you up with songs in a similar vein. I currently have stations set up for John, Bill Nelson, New Musik, Stan Ridgway, Harold Budd, Icehouse, and Sparks. The Harold Budd station is great in that it airs continuous, uninterrupted ambient music by the likes of Budd, Eno, and Cluster.

The damn thing's addictive, so be careful.
