I am legitimately intrigued by this analysis. I've always wondered why I found certain rap so much better than others. I stopped liking the kind of rap that was becoming popular around the time of Snoop Dogg, Dr. Dre, Tupac, etc. Looking at this data, it pretty obvious to me that the stuff on the right I tend to like a lot more than the stuff on the left. Sure enough, I just listened to Aesop Rock for the first time and it is exactly the kind of rap I enjoy.
Similarly, I was happy to see Blackalicious and MF Doom place fairly high in the list too. Aesop Rock is a legend and I have a couple old favorites by him ("Daylight", and that same song's antithesis "Night Light"), but I also find him to be mentally over-taxing at times.
Since you enjoyed your first listen of Aesop Rock so much, for something newer I highly recommend Milo's 2018 album "budding ornithologists are weary of tired analogies". Enjoy :)
