Rainbow just released a triple threat surprise for all of us... the seven-member girl group is still fresh on the kpop scene, but they aren't stopping with Gossip Girl. Even though we've been impounded with girl groups all year, you've gotta love these sweet surprises! Take a listen yourself: Not Your Girl Kiss ????? Despite its questionable name, Rainbow's got some undeniably catchy beats... some of us definitely had our reservations, but with these new tracks, I think many kpop fans are beginning to convert. Rainbow hit the kpop realm less than a week ago and already four songs under its belt. This girl group is still very new, but with these three songs on top of Gossip Girl, they just might be the next big hot issue. What do you think? UPDATE: Another track revealed, check out I Believe!
