for those saying times are different, wondergirls charted higher than twice on the hot 100
if wondergirls had an alternate market like japan for twice (idk if they had one, someone tell me) then wondergirls would be more popular than twice internationally. it's as simple as that.
I mean girl's generation hasn't promoted in a long time and 2nd gen groups didn't have as much international recognition outside of Asia. I feel like you're setting this up to bash SNSD..
