So, this is clever.

A little program sits in your MP3 player and reports what you listen to a website, where it puts up charts and info about what you listen to.

Then it creates a personalised radio station playing the sort of music you listen to.

And then it tells you what people who listen to music like you listen to are listening to — Amazon-style recommendations based on usage.

I’m going to cheat a little and leave iTunes telling it about my favourite music whilst I sleep.
