The only music videos I watch are the ones by OK GO. They always come up with something intricate and mind bending. And they've released another doozy.
If an airplane flies a particular parabolic pattern (the shape of the curve when a ball is thrown) those in the plane become weightless for about a half-minute. So the intrepid team shot this video in an airplane doing those maneuvers. They designed the routine so that every half minute or so they are in a place where they can hold still when gravity returns. What fun! The video is here and the explanation is here.
