On the plus side, I ended up with three free iTunes downloads. Yay! So here's what we're going to do. Recommend up to three songs below. If you feel the need to justify your suggestions, or if you can't vote in the poll but want to make a suggestion, do so in the comments. In a couple of days, I'll do another poll, listing the nominated songs and allowing you to vote for which ones I should download. It's democracy in action! De Tocqueville would be proud.
Edited March 11: Sorry, the poll is now closed. But if you want to see how people voted, it was poll number 259083. (And technically, the poll isn't closed; I'm just no longer going to check for new responses.)
Edited to add: I just won a fourth one on the Big Gulp I bought earlier this evening! Yay yay!
