A Cappella Cover of PSY’s ‘Gangnam Style’ Done by NBC’s ‘The Sing Off’ Winners Pentatonix [VIDEO]

If you watched season three of NBC's 'The Sing Off' you are surely familiar with this group of singers, as the were the winners of that season, but if you're like me and have never watched that show, let me introduce to you Pentatonix. They are getting on the "Gangnam Style" band wagon with their own version of the popular Korean song.

Surprisingly they do an awesome job with the dance track originally performed by the artist PSY, other versions and parodies have been done, but for me, this is the best so far.
