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

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.

I lived in the States from 1996 till 2000. I attended the Berklee College of Music in Boston in 1997. But I wasn't the most hard-working student. I rarely went to school. At that time, I seriously doubted that you could learn creativity in school. Music isn't something you can just learn from other people. Sometimes I regret missing classes.

While I'm grateful for the freedom to express one's self, I've learned there are limits to what language is appropriate and I'm deeply sorry for how these lyrics could be interpreted.

It's not like I'm the most famous person in the world.

For a time, at least, I was the most famous person in the entire world.
