Brown Eyed Soul Young Jun's song for the SBS "Great Doctor" OST is becoming a popular hit.

On Monday, the song titled, "The Song of the Wind" was released, making it a part of "The Great Doctor OST Part 6."

The song is about Choi Young, a Koryo warrior and a man who is in love with a woman, yet feeling conflicted about it and worrying about their future. 

The powerful guitar sound meshes perfectly with the orchestra, which adds emotion to Young Jun's vocals and tells the story of Choi Young's love very faithfully. 

"Great Doctor" OST had included other songs like Shin Yong Jae's "Because of Slow Steps," Jang Hye Jin and MC Sniper's "Bad Person."
