I don’t listen to a TON of rap, so I’m far from an aficionado. I’d say about 20% of what I listen to is rap/hip hop.
In terms of current rap I like I mainly listen to: Kendrick of course, Tyler the Creator, Kanye, Playboi Carti (yeah he’s basically a gimmick but the hooks), and Travis Scott (again more of a hook artist than a rapper). Death Grips if they count. I like a lot of the psychedelic influences these guys have in their beats. As for older stuff, the usual, Nas/Biggie/Pac/Jay-Z/Outkast/Tribe. I consider Nas the GOAT of that era for Illmatic alone. I’d say that album is by far my favorite rap album.
