I have seen recently many akp users talk about twice potential downfall/ decrease in interest amongst the gp. With many alluding to the change in sound. (Same can be said about gfriend)
However then again, I see many complaining about black pinks music, so that is no longer fresh and original.
So how important is it for a kpop group to have a distinctive sound. Especially for girl groups that traditionally have needed to rely on gp since it is harder for them to amass large fandoms unlike boy groups
