Nothing against these groups but they have no actual vocalist.
I don't understand how NMIXX have one of the best vocal lines k-pop has ever seen is flopping in Korea??
Yes, their music is different and slightly disjointed but when Aespa does it they eat it up. (props to aespa cause they do have a great vocal line)
Music isn't the issue I feel like they focus too much on visuals and that is messed up.
