2AM's Changmin has been announced as the next artist to participate in the sixth OST for the KBS 2TV drama 'Ok Gwang Sisters'.

Changmin's soundtrack "The Sound of Goodbye" is a ballad song that expresses the emotional moment of parting. The melancholy piano melody and gradually richening string instrumentals maximize the song's sensorial sounds. In particular, the lyrics emphasize the dramatic moment of parting. Changmin's mournful voice adds to the sad emotions where even without saying anything, the parting between two lovers can be heard.

Changmin soundtrack for 'Ok Gwang Sisters' will be released through various online music sites on June 19th at 6PM KST.
