Group Block B leader Zico produced D-Unit's new song, "Stay Alive."

This song was released today on music sites and is also the first time Zico has produced for another group. 

Zico was able to work the the group through his friendship with D-Unit's CEO. Zico was confident in making a great song for them as Block B had been successful with their past songs.

On the other hand, D-Unit will be releasing the rest of the songs from their album next month.
