The internet, Me, and tailored spam

I realise its pretty much inevitable that my internet usage patterns are being aggregated and are/will be used in the future for marketing directed towards me. I can live with this. I could even go a step further and say I embrace it. And this is the very reason i'm happy at the moment. I allow Last.fm to know what music I play using their funky audioscrobbler plugin in my most used music players. A perfect opportunity for direct marketing. So I was naturally delighted when I got this mail, even though indeed, it is spam. Well done Last.fm.
