Pentatonix does a cover of 'Gangnam Style'

Pentatonix who is an acapella group of five vocalists did a cover of Oppa Gangnam Style and it is ridiculously awesome. You need headphones to the epicness in high quality. It has grazed the one million mark (like any other 'Gangnam Style' parodies and covers) but it is the best cover so far on Youtube. The crazy runs they do with their voices is amazeballs. KEEP ON GANGNAM STYLIN' !
