From my POV. And yes this is very bias but i gotta say it somewhere, right? LOL
SNSD are people who can't exactly sing. Yeah they can dance. But urgh. You have 9 or 10 or dont know how many people in a group. And they're all suppose to sing a 3min song. How many lines can each member get? And all those people like them because they're just the "perfect" girl. You know, fake boobs, bootox and all. Like urgh they're so plastic and fake.
And then you see those fans putting photos of the respective members as their profile picture. HELLOOOOO ITS YOUR PROFILE PICTURE. Can you put your photo in it?
Ahhhhh or maybe it's just me. Hahahah :)
P.S Big Bang (under YG family) is the first korean group that entered the Jap market right?
:D
