As 2009 comes to a close and the gayo daejun events roll in to wrap up the year, it's natural for all of us to look back on the past few months and reflect on With the advent of new groups like 2NE1, 4minute and f(x) as well as the ones that skyrocketed to fame (Brown Eyed Girls, Kara) this year, there's no question that 2009 was all about girl power from beginning to end. This year's SBS Gayo Daejun stage was practically brimming with girl groups with a grand total of eleven girl groups making appearances - 2NE1, 4minute, After School, Brown Eyed Girls, Davichi, f(x), Jewelry, Kara, SNSD, T-ara and the Wonder Girls (in an overseas video message). Each group is performing two or three of their hit tracks from this year, taking us all on a trip down memory lane as we revisited some of the biggest chart-toppers of the year. Without further ado, check out these hot performances with us as we update this post live with videos!
