After singing about the days of the week for their debut single, Mazeltov, the ZE:A boys have gone back to the drawing board and returned with something more bad-ass. Their new music video is inspired by the classic movie, Friends and sees them getting transformed into high-schoolers who brawl. It looks mighty similar to a Japanese movie, Crows Zero but heck you cannot fault their effort. The song All Day is a tune by the Brave Brothers. http://www.youtube.com/watch?v=UzfCIPYT4zA
