Akdong Musician will be singing the OST for Jung Woo Sung's entry for 'My S4 Story'!

Jung Woo Sung, Kim Nam Gil, Yang Ik Joon, and Goo Hye Sun all became directors for the 'My S4 Story' project, where the four actors directed movies filmed with smartphone Galaxy S4 by Samsung.

Jung Woo Sung named his movie '4-rang' (a play on the Korean word sarang or love, as '4' is pronounced 'sa'. Since 'rang' can mean 'with', the title can also be interpreted to mean 'with 4'). He told the story of the innocent first love of teens, and Akdong Musician helped out by lending their voices for the OST of the short film.

At the press conference held at the Seoul Gangnam CGV, Jung Woo Jung revealed a video shout out by the pair, who said, "We really wanted to go to the press conference, too, but since we're in Mongolia right now, we're greeting you like this."

There is no word yet on if or when the OST song will be officially released.
