After two long weeks of music programs postponing their broadcast due to naval ship tragedy, Mnet's M! Countdown revealed a couple of days ago that they will resume their broadcast starting from this week. Today, viewers were finally able to watch the artists perform. Although there were no studio audiences to cheer on the artists, I'm sure they were all cheering them on in their homes. The boys of 2AM were one of the several artists to finally return to perform. Check out their awesome performance of I Did Wrong below! http://www.youtube.com/watch?v=KaFUF_ScLoI
