Calling the artists tank, flop, terrible, etc... because their songs didn't slap is weird. It's not their fault, it's the company. I do believe most groups or even soloist especially in kpop didn't have much power to determine the songs they will debut or cb with. Or they probably given few songs and only can pick one from it, which still not their fault as if what we get is already terrible, imagine how worst the others will be.
This is especially for any antis of any group. Just attack the company. And for company stans, please if the songs is terrible it would not hurt your faves by telling the truth as it's not their fault.
