Last.fm is f-ing sick, you just type in whatever artist you like and they make this radio station built around it. Honestly I have been listening to it for like the last 3 hours check it out www.last.fm it is pretty sick.
Also check this out it's webcam software that doesn't require any downloads it's all in browser. And people can talk to you if they don't have an account I'm telling you in like 3 years this is how everyone is going to talk online (buy now).
Best part is they are all free.
