all the songs doing well in chart doesn't mean necessarily national hit
a national hit is a song who have an impact on the Nation, that's why it's call national hit
and not charting hit
there's just some songs who do really really great in chart
but that lack in term of cultural impact among the nation to be call a national hit
and i think AIIYL is this kind of song it have the charting to back it up
but the song is nowhere near Red flavor, gee, cheer up etc... in term of cultural impact on the nation
you don't see koreans bring it back every time they are making post about national hit on theqoo etc...
This is what i meant but you explained it better than me lmao.
Anyways i agree with you
