If you compare with songs released pre 2020 you dont really know much about the korean charts. Not saying one song is doing better than the other, but ul, likes, streams, digital points etc are much much lower these days.
They were also unlucky to release just before IU had a comeback, none beats IU in the first 1-2 weeks no matter how good they are doing. If not for that they would still be #1 on th/e charts that matter.
based on what? brave girl beat all national hit with just gone viral?
if anything, stream become more popular these days
