New radio on the blog

Last.fm: http://www.last.fm/

Absolutely great!
You sign up (it's free), type the name of an artist and... you're on! Listening to your favorite artist, similar artists you might know already or make some great discoveries, old things you haven't heard in ages...
Not all the artists nor all the tracks are available but it's really cool and building up. Add your favorites to your playlist and for a small amount a mont, you can even have your own personal radio!
Enjoy!
