He's got a great tone to his voice, great range, and his singles from his albums are some of the catchiest songs I've ever heard. His two most famous songs are ê¸°ëŒ€ (Expectation) and ì•ˆë¶€ (Greeting ft. Byul). ê¸°ëŒ€ is definitely one of my favorite songs. The chorus is amazing and the melody is incredibly catchy. ë’·ëª¨ìŠµ (Back) from his 2nd album is also reallly good.
