I've got to wear sunglasses everywhere, all the time, even if its indoors or at night time, to be recognized. That's part of my job. I cannot take off my sunglasses. For me, staying in the United States was so dark because I can't take them off.

I never expect I would become a K-pop star.

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.

Thanks to many great K-pop singers, the groundwork has been laid for more Korean songs to be readily accessible to an overseas audience via channels like YouTube.

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.

We are just at the studio, me and my choreographers, we are spending like 30 nights and we are thinking, what is my next dance move? Because in Korea there are huge expectations about my dancing. So it was a lot of pressure.

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.
