How many tracks have you downloaded from the iTunes Music Store

I was just fiddling with iTunes and I clicked on the 'Purchased Music' smartplay list that Apple ships with iTunes and I see that I have 154 Songs (which translates to 8.4 hours or 506.9 MB's of music) from the
iTunes Music Store.

The name of that playlist is a misnomer because I sure as heck didn't purchase 154 songs from the iTunes Music Store.
There was the first Pepsi/iTunes promotion (during that time I was a heavy Pepsi drinking, having given up Pepsi I am sadly just heavy now), and then the spate of free samplers from Apple, and I received an iTunes gift certificate for Christmas, and let's not forget the track of the week.  I have probably actually only purchased 5 albums from iTunes, which would account for a third of those tracks in the 'Purchased Music' playlist.

How many tracks have you downloaded from the iTunes Music Store? What is the ratio of bought and paid for songs vs.
free tracks?
