I was told about Last FM by the lovely Melanie. Thought I would share it with you all as it's my new favourite internet attraction. Last FM is an online radio (kind of) site. You can log in and place the name of your favourite artist and it will play you tracks from similar artists (amongst its other attractions). Nothing like broadening your taste in music! Trust me, you'll become just as addicted as I have become in the past few hours.
