Found this via Tom Coates - the idea is that if you've set yourself up with Last.fm recording your listening habits through their iTunes plugin, you can graph your listening habits over a period of time.
Predictably mine is lots of AFX, Scientist and Broadcast, and also an awful lot of tiny lines which are just one track. I listen to iTunes on shuffle an awful lot. If you want to check out the rest of my graph, for some unearthly reason, go over here.
