On the September 10th episode of 'Show! Music Core', MBC experienced yet another live broadcast accident, which forced the show to start right back from the beginning. About one minute into the broadcast, a camera blanked out, similar to the blank out that occurred during Chocolat's debut stage earlier this month. The screen then went back to the beginning to start all over again. The artists who experienced this unfortunate mistake were pop-rock band Sweet Revenge, with their title track, "Rule Breaker". This is Music Core's third live broadcast mistake of the year, starting with MC Jiyeon's voice being heard during F.T. Island's performance back in June and Chocolat's two-second black out on September 3rd. Source + Photos: Mydaily via Naver
