Mnet's "M! Countdown" is back with another episode of great performances! Besides the usual stages, Koyote, Dal Shabet, and Nine Muses made their comebacks this week. Elsewhere, rookie girl groups Chocolat and Blady made their debuts. It was a hot battle between Super Junior, SISTAR, and 2NE1 for the #1 spot on "M! Countdown" today, but in the end, it was Super Junior who got their second straight win for "Mr. Simple"! Congratulations to Super Junior!
