Not the reply you're looking for OP, but I never saw the appeal or Charli XCX. Nothing I ever heard sounded even half as good or original as her fans seem to pass it off as.
Yes, I like both and I don't consider Charli good at either. Very much feels like "how do you do fellow kids" when such a major-label supported artist is copying underground sounds.
Not a huge charli fan or even hyperpop/club music fan, but I've been enjoying Brat. Just feels like club music that isn't horribly derivative and boring. The production is good and the lyrics are actually somewhat interesting and meaningful.
Do you have an album you would recommend as better than Brat that's trying to achieve the same thing?
