i think that if aespa continues at the rate they're going where their songs are hits for the next few years, even if they never hit next level level again, they'll maintain a top 3 position if not no. 1. i can see them having the same trajectory as snsd and twice even if they aren't a group that gets the ngg title.
idk about anyone else or how any of the other groups will rank because they literally haven't debuted yet, but i see no reason for aespa to fall that hard. and whether anyone likes it or not, 3rd gen is coming to a close, and our 3rd gen faves are going to keep falling to make way for the new gen.
