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.

Queen and Bon Jovi, Aerosmith and Guns N' Roses - I had a huge rock-band mania. I play a little bit of drums.

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 really like the P!nk song with the guy from fun., 'Just Give Me a Reason.'

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

Everything moves way too fast.
