with those examples did they work more in the rap demographic or rockyou can also put jay z on a whole album with Linkin Park or run dmc with aerosmith and it works, ...collaborations working don't mean someone isn't still mainly subgenre A & B while the other artist is subgenre X & Y. genres don't refute people coming together

run dmc already had a rock sound second album was called kings of rock for a reason.
you tend to forget it’ll also create tribalism. and would have people making new sub genres everytime someone expresses themselves differently. look at carti they calling his shyt rage/emo rap when he just expressing himself in a weird way. its unnecessary. now if carti wants to tone his shyt back and make shyt like nudy does they gone say he sold out cus he not “emo rap” anymore. it will make rap artist less dynamic cus they’ll have to really stick to a style. drake could barely experiment with that house album imagine if he got locked into a subgenre and wanted to do that.
