26. "Tim McGraw" (2006)
We knew she was trouble when she walked in – or at least we should have guessed from her debut single. You couldn't make this up – a nervy high school kid shows up with a country ballad she whipped together after math class one day, about slow dancing in the moonlight to the pickup truck radio: "When you think Tim McGraw/I hope you think of me." Within a couple of years, she's an even bigger star than McGraw is.
Best line: "He said the way my blue eyes shined/Put those Georgia stars to shame that night/I said, 'That's a lie.'"
