The girls' debut MV "BOOMBAYAH" now has over 1 million likes on YouTube. They're the first K-pop girl group to reach the feat, beating out even sunbae�girl groups that have been out for much longer. It's even more impressive if you take into account that the MV has been out only for about five months.
