Would you agree that having a song on a drama OST and also showing up on the show constitutes a double bonus? And, wouldn’t it be made that much sweeter if that song was one you wrote and composed? Indeed. Such was the case for G.O and Mir’s 알고있었어 [I Already Knew]. They hit the trifecta for Channel A’s drama, K-pop 최강 서바이벌 [Strongest K-pop Star Survival], by appearing in the show, having a song on the OST, and being the writers and composers of that song.
