I took my niece Tianna to her first concert years ago and it was to see Taylor Swift. I'd never really heard any of her songs at that point, but this one was the main one she did that stood out that night. I know it's kind of lame for a definitely-not-fifteen-year-old to love this song, but I tried to fight it for years before giving in. It's so goddam catchy. And the line, "Back then I swore I was gonna marry him someday but I realized some bigger dreams of mine"?! C'mon, that's gold.
In any case, I know this song's old and everyone knows it already, but it's literally still on my iPod and I love it to pieces.
