Girls generation has over more 6 millin album sales(if iam not wrong) cummaltive sales second after to Twice among kpop girl groups if bp releases another 2 albums or maybe 3 ( a boy can wish) does bp can beat SNSD and second girl group in album sales
i just dont think they're gonna release enough music while they're active. But maybe Blinks will prove me wrong and they'll sell like 2 or 3 million for their next albums.
i don't know. blackpink are extremely popular but rarely release music so at the moment they have to rely on the fact that their fans will keep buying their previous albums a lot
