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

If a Korean artist reaches to the top, we're all ready to stand up and applaud for him or her.

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.

In Korean, my lyrics are witty and have twists. But translated into English, it doesn't come over. I've tried writing in English, just for me, but it doesn't work. I've got to know everything about a culture, and I don't.

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.

Before 'Gangnam Style' I was not a good attitude artist.

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.
