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.
Congratulations to the girls! If you haven't seen their MV yet, you can do so here.
