There's a video doing the rounds this week called Dancing in Movies, and it's proving to be impossible to avoid. 1.5 million plays on Vimeo. Virality huh... But it's no good. The tracks he chose are agonisingly undanceable and it doesn't match satisfyingly with any of the actual dancing, much of which is amorphous. It's just random clips of dancing with a weak musical backing.
This one, on the other hand, from three years ago, is an absolute classic. Every clip is achingly skillful, the track (Uptown Funk) is the most leg-twitchingly danceable track ever produced, and the dancing actually fits the rhythm of the song, which you'd think would be fundamental to a project of this type.
