I have been listening to Korean musics these days. My point of view in Korean musics were basically can be grouped into two: pop or old pop.
One day, I came across a Korean singer, Busker Busker's Jang Bum Joon (장범준). He has good ability make his own music from both pop + old pop. Even though he is not much aged at all, he can remake some of the old pops turn into his modern style. He has a special vocal sound which defines who he is. Also, most of his songs are relaxed and easy-to-listen.
Sometimes you would find his songs are some-what repetitive and similar style in most of the songs. However, that is what I like about him. He has his own colour to his songs.
Here are some of his songs I have been enjoying listening to lately
