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.

My original name is Jae-Sang Park, so it's totally different.

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.

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

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.

I've always tried to come up with funny dancing since I was young, to attract girls' attention for one thing. It's got to be funny. I can't pull it off with serious dances. That's not me.

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.
