WINNER: Taylor Swift
Taylor Swift was the night's big winner purely by the numbers (she picked up four awards, more than any other artist), but her final acceptance speech — for Artist of the Year — struck the perfect earnest tone. "My lucky number is 13, and so far you guys have made 2013 the most magical year of my life so far," she said. "I cannot thank you enough. This validates that if you voted for this that we are heartbroken the same way and we fall in love the same way. . . I'm 23 and I have no idea what's going to happen with my life!"
