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

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 never expect I would become a K-pop star.

My lifetime role model and hero is Freddie Mercury of Queen.

I just made my album. I did my best, and I uploaded the video just at YouTube. That was all.

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.

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.
