>It’s hard to say that Chappell Roan is particularly derivative of anything

I've never heard of her, but the first search result I got is this: https://www.youtube.com/watch?v=1RKqOmSkGgM

It seems very derivative to me.

And FWIW I think there's plenty of high quality and original/creative music out there nowadays. But the 'top 40' category does seem quite stale and boring (judging by the music I hear in shopping malls/bars...).
