It sure feels like it's been forever since we've last seen ZE:A on stage! The boys surely must have been aware that we were lacking some ZE:A love in our lives because they upped the ante on today's Music Core stage! The vocals and dancing were definitely on point as the boys reminded us just how addicting their song All Day is. Nine sexy boys on stage doesn't hurt either. Though the competition is filled with several talented groups and solo artists, the boys are still hanging tight. Did you miss these guys as much as I did? No? Check out their performance below and let's see if they can change your mind. http://www.youtube.com/watch?v=R055g0iQBB0
