I can't with people that didn't even know kpop existed until a few years ago thinking they know anything about 2nd gen
I was here during the 2nd gen, the competition was enormous, nothing like you see nowadays
And how dare you guys leave out f(x) from the list! they were the 2nd best selling gg after SNSD during their "peak to disbandment" years
Back at the time, achieving 100k sales was massive, nowadays you sell that in 1 day. So comparing album sales etc is completely ridiculous
