Taylor Swift is so excited that "Shake It Off" is No. 1 on Billboard's Hot 100 that she shared a treat with everyone: a behind-the-scenes look at her music video for the song. The video for "Shake It Off" is almost at 47 million views, and the outtakes video features a couple of interviews with Swift about her prep for the rigorous shoot. Things we learned: she hates running, she had to do "a million" basket tosses, and she wants you to move to the beat of your own drum. Take a look!
