It's tiring to be asked the same questions all day long: 'What is Gangnam style?' and 'Teach me how to dance.'

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

There's a lot of variety of musicians in Korea. I cannot say they are the best in the world, but I can say that Korean artists are really dynamic artists, so I am going to show that from now on.

Everything moves way too fast.

I cannot learn creation from other people; I've got to do it myself. Now, honestly, I regret not studying - I don't know about harmonies, or anything, so if I'm composing a song, it's really hard.

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

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.
