Now that Psy‘s ‘Gangnam Style’ has blown open the door for K-Pop to go mainstream in the U.S., who might be dancing through that door next? Our money’s on South Korean foursome 2NE1, one of the hottest K-Pop acts in the world.

In fact, they were named Best New Band in the World last year in an online vote by viewers of MTV Iggy. The girls have performed live with the Black Eyed Peas, scored multiple Top 10 hits on Billboard’s K-Pop Hot 100, and played their first American concerts last year.

What does their music sound like? It’s poppy, colorful and upbeat, like their K-Pop No. 1 single ‘I Love You’ and the catchy ‘I Am the Best.’ They’ve even released English versions of some of their songs for those of us who are hopelessly monolingual.
