PSY says he knows why "Gangnam Style" became such a universal smash -- and it has nothing to do with his rapping.
The Korean sensation tells the Hollywood Reporter, "You can say it was all about the video, right? But I'm thinking, people are already done with the video. They’ve already seen it, and even if they repeat watching my video, they can do it at most, like, 20 times. Then you get tired of it, right? So it has to be the dance… [Because] they make it their own. They can improvise in different circumstances."
