Pandora changed my life

Pandora.com is a wonderful website created by the Music Genome Project. You go the site, which is totally free, register, and then give them an artist that you like. Based on that artist, they play streaming songs that you may or may not like. You can then choose if you like or dislike the bands they play, and with that additional information they refine their choices even more.

It's truly amazing for the fact that it's free and a great source to find new artists that you may never have heard of. Everyone needs to check it out.
