There's a reason why Girls' Generation is one of the top reigning K-pop girl groups!

It wasn't too long ago when their "Party" MV hit 10 million views and now they've hit the whopping 20 million view mark! They've done this in less than 3 weeks, which is a huge feat for even veteran groups. A big congratulations to the girls!

If you haven't already seen the MV, you can check it out now!
