2016-2019 twice was #1
From 2020 onwards bp is #1 and i don't think it's going to change given how other ggs can't compete with bp on international level and even in SK last year.
Also some people bringing in cumulative sales aren't helping their argument. Blackpink hardly had comebacks yet are the first gg in 52 years if i am not wrong to sell 1M album copies. Mind u even before this their album sales were good.
