The original author was pretty clear about the limitations of his work. I certainly would like to see an updated version, so I'm glad you got nerd sniped and not me. I look forward to see your super accurate updated version in a few months ;)

I've wanted to see a version that segmented rappers by topic clusters of what they rap about, with fine enough details that you could take something like "drugs" and drill down or aggregate specific ones, and even have some sentiment data as well like pot good/X bad. It'd be fun to see who has the most unique general topics and topics only covered by one rapper. I can see how that might be biased in favor of total lifetime output, but perhaps not. My favorite dead rapper is Eyedea, his album output didn't exceed the 35k word minimum for the vocab list but his topic breadth was pretty wide. I've thought LLMs might be good enough to do that for a lot of songs now, if they don't have a panic attack over the language anyway, but I haven't experimented. Maybe someone else can be sniped into doing it~
