For the last few weeks my wife and I have been enjoying the series of HP comercials in that uses The Cure's "Pictures of You" as a soundtrack. The first time I saw it, I went right out to iTMS to see if they had it, which they did. I happened to notice that it was listed at number 8 on top downloads for the Cure and attributed it's popularity to the HP commercials.
I didn't buy it at the time, but went back a few days later a noticed it had moved up to number 4 on the list. Again, for reasons I can actally explain, I didn't buy, but went back last night and it had moved to the number 1 spot, and like the good lemming I am, I hit the purchase button.

It's so nice that other people are running ads for iTMS, even if they don't mean to.
