MBC's 'Music Core' is back once again with another fun and exciting show! For this week's episode, 'Music Core' aired footage from last week, as a baseball game interrupted its original broadcast. As such, the audience got to see comebacks and performances from artists who have already made their comebacks. -- A Pink, Son Ho Young, and the Buga Kingz returned to 'Music Core' this week, while SECRET said goodbye. Other performances from today's show include Wonder Girls, T-ara, B1A4, LEDApple, Boyfriend, RaNia, Norazo, X-Cross, 4men & Mi, TRAX, Tim, Suh Young Eun, Electroboyz, Wink and F1RST.
