Taylor Swift's highly anticipated album Red was released this week, and was heard by millions in the process. No, really. More than four million copies of the album were sold in just one day. (And we're betting that her ex-boyfriends were a part of those listeners.) Now that you've had a few days to digest the new music and listen to the songs over and over again, we've gotta ask: What's your favorite song? Our personal faves include "All To Well" (ahem, Jake) and "I Knew You Were Trouble." Seriously, I can't stop bopping at the work desk over here.
