Kim Jong Kook a formal member of a famous dance group "Turbo" in the 90's became a solo artist after Turbo disbanded. When he first came out as a solo artist he did not get as much attention, yes he had the fans from Turbo period, but it was hard to grab that public attention when you couldn't produce the hit songs as a solo artist like you used to.
But that problem was soon solved as soon as this song came out. A simple lyric and chorus which many people could repeat after is always an essential to a hit song and this one had it. It gave him a leverage to show up on more TV shows like X man, which was probably the most famous show in korea at the time. After that he has been successful in almost every single album he released. Even though he is now having quite comical character or "Spartan" image in the show Running Man, there are numerous amounts of song that you must listen to before estimating or even judging how good he is.Listen to Podcast(M4U with Denny) in
