Most if not all the new girl groups after Black Pink have similar if not the same concept.
CLC, G idle, Everglow, Itzy and I don't know who else all have very similar girl crush music.
Just replace the members of one group with those of another and boom, you get quite the same thing.
The only difference I see is with Itzy dancing harder and G idle singing more and that's it.
Their music is not as unique and different as that of Snsd, 2ne1, Fx, T-ara or Red Velvet, Black Pink and Twice.
EDIT: I'm not saying that newer ggs sound like Black Pink because obviously they don't.
