The newest SM girls on the block�f(x) performed their new single NU ABO on Music Core! With an already hot dance and tons of sexual appeal, each and every performance from these girls is becoming a gem for fans to enjoy. Although netizens are accusing Music Bank of faking scores and denying the girls a win, there should be no problems with Music Core as there is no winner period. The girls gave another stellar performance, and I'm sure they made fellow SM artists/MuCore MC's Tiffany and Yuri proud. http://www.youtube.com/watch?v=H4pcNupLiBk
