I wanna know how the guy found this clip to begin with and figured out the synchronicity. It's like the 1989 Crystal Light national aerobics championship or something. That's just nuts.
He must have done a little editing, it would be too over the top to have that sort of sync to the lyrics(not just the beat), but I have to admit it was really well done (that Taylor Swift song is a guilty pleasure of mine… normally not my cup 'o tea but that one gets me).
