All the people in Korea are cheering me like I'm a gold medalist or something, so I have a responsibility to my country.

If I say, 'Hey, I'm Psy.' 'Psy?' 'The guy from the video on YouTube?' 'Oh.' I hate that. I've got to be more popular than the video. So I need to keep promoting myself.

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...

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.

Gangnam is a territory in Seoul, Korea. I describe it as noble at the daytime and going crazy at the night time. I compare ladies to the territory. So - noble at the daytime, going crazy at the night time - and the lyric says I am the right guy for the lady who is like that.

I need to show the world that my final goal is to perform huge concerts like Madonna.
