Pandora's Music Box

Brought to you by the Music Genome Project: Pandora. Customize your own internet radio station based on genres, artists and songs you like. Popular or obscure, you'll probably be able to find it here. And based on the artist or song you give it, it will find other artists and songs that are similar. This is by far the coolest thing I've found in a long time. It's totally customizable, tell it what you like, tell it what you don't like, save stations you've created and share them with others. I found it awhile ago, and have been meaning to share it. A lot of you have probably already discovered it and tried it out, but if you haven't you should definitely take a look.
