To the U.S. and the world, I'm just known as some funny song and some funny music, some funny video guy. But in Korea I'm doing one of the biggest concerts; it's not a dance music concert. I'm playing with the band, so I change my every song to a rock song.

There's no time to be bored. I'm so busy doing the horse dance...

The fact that I'm shouting that I have Gangnam style makes people crack up. Imagine if Brad Pitt was singing the song - would it be funny? A twist is important when it comes to writing lyrics.

The basic principle I have is that what is most Korean is what is the most international. I don't want to come here and act like I'm an American. I want to showcase the dynamic potential Korea has, and I want to prove that as an artist.

My wife looks at the person Park Jae Sang and the singer who goes up on stage, Psy, as different people.

Queen and Bon Jovi, Aerosmith and Guns N' Roses - I had a huge rock-band mania. I play a little bit of drums.

The world's most famous and popular language is music.
