Tracks of my peers

Spotify have published a list of their 100 most listened-to tracks in 2009, based on the number of streams in their six launch countries.

The top 10 are:

1. I Gotta Feeling by Black Eyed Peas
2. Right Round - Amended Album Version by Flo Rida
3. Sexy Bitch (Featuring Akon;explicit) by Akon, David Guetta
4. Poker Face by Lady Gaga
5. Halo by Beyoncé
6. Use Somebody by Kings Of Leon
7. Boom Boom Pow by Black Eyed Peas
8. Ayo Technology by Milow
9. When Love Takes Over (Feat.Kelly Rowland) by Kelly Rowland, David Guetta
10. Kids by MGMT

A pleasing (if surprsing) lack of Michael Jackson, but I don't think I was previously even aware of 2, 3, 8, 9 and 10.

Who is David Guetta? With any luck, I won't find out.
