I actually thought "Blown Away" was so overrated when it came out; now it's among my top 5 Carrie songs ever. I love the musical structure, and how different it is from anything on radio right now. And of course, no one could pull off the vocal performance the way Carrie does.
I'm not voting in my own poll, but I'm siding with "Good Girl." I love that the musical structure is so complex, yet it works so well. The lyrics are fun, too, and there are some gems in there. GG is the perfect hybrid of country and pop; it's a breath of fresh air compared to what most artists are doing right now. Mostly I think it proves Carrie wanted to take a huge risk, and I commend her for pulling it off so flawlessly.
