#2. Chandelier

It's amazingly well done.  At number 2 comes Sia's Chandelier, which features the eleven-year old Maddie Ziegler.  Maddie's dancing is amazing, and she is an incredible and talented dancer, not just as an eleven-year old, but as a dancer in general.  It is heartfelt and every once in a while, you can see the typical sweet goofiness of an eleven-year old seep through.  It's also refreshing that the singer herself doesn't feel the need to be in the video and take all the credit.
