hell naw
the issue is people are snobby because they feel like one is lesser than the other and feel they shouldnt or cant like it and try to relegate it into subgenres when its really just skill tiers.
they all rapping the dynamics are not too far apart. jay z and big sean as artist are not that different its just a skill gap.
rock is different because punk rock and death metal are overall different from the dynamics of the production and vocals and the lyrics.
acoustic rock bands arent going to have a synth player like korn has.
the dynamics in rap arent too far apart from each other enough to warrant subgenres. you can get pharoah monch and jay z on the same song and it’ll work fine. 21 savage and drake just did an album together.
you cant put ozzy osbourn in sum 41 and expect it to work. in rap you can put smino on the hook of a kodak black song and it can work. hell kendrick and kodak just made a great song for his last album. this cant be done with different styles of rock like it can with rap
