Yes, i said it. PSY has created the best piece of music and dance combination of our generation, and probably more to come. 1/7 of the world has seen Gangam Style, in fact as of typing it has 1,038,890,296 views. It is not only played in North America and Korea, its birthplace (which is even more amazing), but all over the world, unlike every-other "popular" song.
The song has been popular for months, and will continue to be so. Infact, CNN published an article on how gangam style should die. It obviously has not though, and will continue to gain views which proves PSY is a musical genuis.
