This week, all eyes are on two of K-Pop's biggest girl groups - 2NE1 and Girls' Generation - as they make huge comebacks and face off in the charts.

Both groups have huge, passionate fandoms and a lot of critical support from both domestic and international media, making the battle for number one all the more intense and intriguing to watch.

But while you are trying to decide which is better, Girls' Generation's Mr.Mr. or 2NE1's Crush, why not take the time to step back and consider the multitude of number one hits from some of K-Pop's other popular girl groups.
