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.

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

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

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.

When I signed with Scooter Braun and I decided to go overseas to promote my song, the only concern was how should I communicate with the public and the audience with my language. Scooter and I talked a lot about that: should we translate or not? Finally we didn't, and I think that was a really good decision.

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'm not that good looking. That's why 'Gangnam Style' works. If someone handsome uses that phrase it's just awkward. But if someone like me uses it, it's funny.
