A friend told me about the site, Pandora Internet Radio. The url is http://www.pandora.com. There are thousands of musical selections on the site that you can listen to.
You can read about the Music Genome Project here: http://www.pandora.com/mgp.shtml
On the site, you can select a composer, artist, or specific song. As I type this, I'm listening to a Bach concerto. Very nice! Free!
