I had to go on Youtube to listen to some of the music mentioned here, as I'm pretty out of the loop on it. Given what I heard I honestly think we're basically at the point where AI can generate equivalent or even better music. It's just very simple and doesn't feel particularly innovative or noteworthy.

Point being, I think it's likely this person is one of the last pop stars.

Actually, as I'm writing this, I realized that probably the music being produced by this person is actually done by a computer. So, maybe she's in the first wave of totally artificial pop stars.

It makes me sad to think you have formed this opinion on her more than decade long career that spans a variety of genres and many collaborations based on a few brat songs you may have listened to

The novelty in pop music is not usually in the harmony. The novelty is usually in the presentation. The idea is that you hook the audience with familiarity (nostalgia) and then keep them with a novel expression of it. In recent years, this means really strange synth patches and vocal effects.

Maybe you could tell all her fans how stupid they are and shouldn't enjoy her music.

Why not save them from themselves with some of your approved recommendations?
