Some of the people who hate on aespa, NCT, Stray Kids, and Itzy for noise music stan BTS and Blackpink. They also have songs that are "noise music". Let's not forget Kill This Love or IDOL. I'm not hating on anyone, just pointing out the hypocrisy.
It just makes no sense to claim that noise music is ruining K-pop because half of the time the people that make these claims only listen to a group's title track. Then they go on to say "ThEiR eNtIrE DiScOgRaPhY iS nOiSe MuSiC"
Seriously. Take an hour to listen to any single one of the discographies of the groups that I mentioned. You'll realize the entire thing is a fallacy. It's a narrative K-pop stans created to hate and shame other groups.
