After School vs SNSD

I've read about the all-female korean pop group, After School, before but I was never interested enough to watch their music videos. Until I got curious about one of the members, UEE. She was part of the cast of the TV series, You're Beautiful, and I found out that she was a singer too.
I then searched youtube and found this group performance of their latest single, BANG. This is my current fave song next to Super Junior's Sorry Sorry!!! ha!ha! I listen to it over and over again while surfing the net. I even like this one over SNSD's new song, OH.

BANG by After School


OH! by SNSD
