Last FM - what are we really listening to?

Fourstar's earlier post made me think how I've become strangely obsessed with Last FM and also the song count on iTunes. I love and also hate the fact I now know what I actually listen to the most rather than kidding myself I mainly listen to cool stuff....

So question is, what are your stats on Last FM, and do you need to justify them? I've been on it since April, total of 4300 songs listened to, and my top 5 artists over that time are:
1. Sonic Youth - 249 listens (partly induced by a bout of obsessive listening around the time I went to see them live, partly by the fact I have about a billion songs by them)
2. Burial - 127 listens (I blame fourstar)
3. Arctic Monkeys - 103 listens (I'm a little surprised by this)
4. Toots and the Maytals - 98 listens (my favourite summer reggae tunes)
5. CSS - 94 listens (just a great album)

And in case you're wondering my most listened song according to iTunes is Deep In The Horchata by Death Vessel, which I have listened to 34 times since getting a new computer and reinstalling itunes in Jan last year.
