This South Korean band is among the most influential boy-bands in the globe. EXO debuted as a 12-member group in 2012 with a focus on Korean and Mandarin songs. Its debut album XOXO sent fans in a tizzy and won it awards both critically and commercially. "Growl" broke every record in the country and put EXO in an enviable spot of being the first Korean band/artist to gross over a million copies in the span of 12 years. Now comprising of nine members, this K-pop still reigns in the hearts of fans with sold out concerts bearing testimony to its popularity.
