The only bands/groups that have rappers that I’ve listened to are Beastie Boys and Red Hot Chili Peppers. The latter is still active so I’d say Anthony Kiedis for the Chili Peppers.
As for individual rappers, I haven’t really listened to any, but I have listened to “My Name Is” by Eminem (my dad said that I shouldn’t listen to it but he played it anyways), “Empire State of Mind” by Jay-Z, and also part of “Old Town Road” by Lil Nas X. I like the last two the best.
