Everyone from that thread that said Apink should be placed in front of f(x) in the top 10 are new to kpop.
Apink was big but they weren't f(x) big. f(x) sold more albums per release and had way more YouTube views (the two areas everyone counts).
This is especially true since we are talking about 2nd gen. What Apink did AFTER 2014 doesn't count cause its 3rd gen. And even then their albums sales don't come near to f(x) album sales.
I have no problem admitting when a group was bigger than my faves. But Apink was just one step above Miss A. f(x) was three steps above Apink.
Free education. How many of yall missed these? Everyone I'm sure.
