Although 2009 was speckled with female debuts like T-ara, 2NE1, After School and more, the wave of testosterone hit with full force with the return of groups like 2PM, SHINee and Super Junior as well as the advent of BEAST and MBLAQ. This evening, many of these groups returned to the stage to perform their chart-topping hits at KBS Gayo Daejun / KBS Gayo Festival. I think these performances really speak for themselves, so check them out now: Lee Seung Gi with Love Is and Will You Marry Me? JYP with No Love No More. MC Mong with Horror Show. Leessang with Woman Who Can't Break Up, A Man Who Can't Leave SHINee with Ring Ding Dong. K.Will with Dropping the Tears. Kim Tae Woo with Love Rain. 2PM with Heartbeat + I Hate You + Tired of Waiting. Super Junior with Sorry, Sorry.
