Younha & Epik High

비밀번호 486 - Younha
Love Love Love - Epik High

K-pop has the goofiest background dancers. Check out the guy at 3:08 to 3:15 in the video. There is also a lot of lip-syncing in K-pop performances but since they're singing each other's songs, it's all live (Younha forgets some lyrics at 3:20).

Younha is only 19 years old and she has already released 9 singles plus an album in Japan and 2 albums in Korea. She also sings in English... very talented.
