Mnet's M! Countdown is back again on October 14th with another weekly fun-filled music show, and this episode is packed with exciting performances. The most anticipated stage today would definitely have to be 2PM's, as they performed their addictive comeback track "I'll Be Back". Younha also has a comeback stage today, singing her rock number "One Shot" for the audience. There was also a debut stage for Superstar K2's Kang Seungyeon and a follow-up performance by rookie girl group, Nine Muses. It was a rematch between 2NE1 and B2ST this week once again for the #1 spot on M! Countdown. In the end, it was the B2ST boys who came out on top and ended 2NE1's four consecutive #1s run on M! Countdown tonight, just like what they did on Music Bank last week. Congratulations to B2ST on a 2nd win for "Soom"! Other performers for today include 2NE1, F.T. Island, Se7en, miss A, Co-Ed, U-KISS, Eru, Chae Dong Ha, Supreme Team, B2ST, and J-Lim. Check out the performances below. Supreme Team covered Shin Seung Hoon's "Romeo and Juliet" Co-Ed boys had a minute long dance routine at the start. On MCD Paparazzi, miss A members celebrated maknae, Suzy's 16th birthday. For MCD News, B2ST, Supreme Team and U-Kiss did some drawings.
