Five dudes playing the crap out of one piano. Usually we would use this as an opportunity for a well-placed sexual euphemism, but the song they chose to play kind of sucks all the life out of it: One Direction's "What Makes You Beautiful." Let's face it: Everything about that song just sucks. Shame to see such talented musicans waste the fruits of their talent on covering Brit-Pop boy band garbage. That said, it's still kind of a f*cking cool video.
