www.last.fm Last.fm is a UK-based Internet radio and music community website and it's totally awesome, it is pretty accurate at guessing what type of music you fancy listening to. All you need to do is tell it 'i want to listen to stuff like chemical brothers' for example and it will stream a constant taiored radio station to you for free, if it plays something you don't like, then click a button and you'll never hear it again. It remembers the choices you make and your stream changes according to your tastes.
