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

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

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.

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.

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

Everything moves way too fast.

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