I mean I am not a snob, what you think is the best rapper or hiphop music is fine by me. I am from the 70s, the hiphop I listened to back in my teens is considered oldskool and so is my top 8 top of my head.
KRS, Kool G Rap, Rakim, Mike Gee and Baby Bam from the JBs, Kool Keith, Chuck D and Flav.
There is so much good hiphop out there, I could ramble on everyone I listen to.
