I've never expected to see his name here. I liked 이등병의 편지(The Army Private's Letter), 일어나.
Some of my favorite Korean songs are 끝이 아니길, 사랑했나봐, 너를 보내고(by 윤도현) / 비망록, 겁쟁이, 나에게로 떠나는 여행, 사랑은 가슴이 시킨다(by 버즈) / 나를 슬프게 하는 사람들, 너를 사랑해(by 김경호) /Starry Night(by 김종서)
As for Japanese songs, I like most Garnet Crow. If you like R&B, you would like Chemistry(Pieces Of A Dream, Two), EXILE(Kiss you, Together, Your eyes only), Hirai Ken songs(He's a famous R&B singer. Hitomi wo Tojite, Aika).
