On the July 29th episode of KBS's 'Music Bank', the ladies of Brave Girls finally made their comeback with their title track, "Easily"! Their comeback mini-album, "Back to da Future", includes a variety of different genres with inspiration from the '80s and '90's. Their title track in particular is a medium tempo song of the reggae genre that's both easy to sing along to and addictive. The song features the leader of Korea's reggae scene, Skull, and is produced by Brave Brothers. Skull praised, "As a rookie girl group, it's difficult to take on a wide range of genres. 'Why So Often' best exemplifies the girls' distinct color and combines a reggae style that's mainstream enough to capture the hearts of the public." Brave Brothers also revealed, "It's the best song I've ever made in my life thus far." Check out their comeback below! Source + Photos: Sports Chosun via Nate (2)
