D4 is Blackpinks biggest hit it`s bigger then Bad Boy for sure, it would be better to compare with something like Red Flavor since it`s more intresting cuz D4 was bigger internationaly, but Red Flavor was bigger in Korea
I don’t know. D4 would still pull through over RF in Korea too when you look at the stats. Plus, it topped Gallup. Red Flavor did have more longevity in the top 100 and does usually place higher in the summer, but D4 was typically higher outside of that season. But it’s much closer than this question.
