2NE1's "Ugly" is an electronic dance track, a genre that the group has come to represent in Korea. Infused with electronic-infused rock guitar, The song's upbeat rhythm is contrasted by its morose, self-criticizing lyrics. In it, 2NE1 sings and raps from the perspective of young teenage girls who are unsatisfied with their appearance and hate the fact that their "ugly" face prevents them from being loved.

Miss-A sings a powerful chorus telling their cheating boyfriends to leave for good.

Miss-A, who has two members -- Fei and Jia -- of Chinese descent, also has a sizable fanbase in China.
