I love a lot of Kanye's earlier work in the 00s I think that probably puts him somewhere between 10-15 maybe a bit higher. But what great beats has Kanye made recently? Does he even still make beats? RZA had a crazy run in the 90s and thats puts him up there whenever these discussions come up, so I don't think he's underrated as such - but longevity is important also.I’d argue RZA is the most underrated producer. People REALLY gloss over how much he achieved in such a short period. I feel like RZA gas a true GOAT argument right up there with Dre, Kanye, and Q-Tip
I mean Pete Rock is still making great music 35 years deep in the game and Dr Dre's production on that Marsha album was kinda impressive as well - the real Kanye needs to come back to get back into that top 5 hip-hop producer discussion. I am looking forward to the LL and Tip project so maybe more people will give Tip some more credit providing the project matches expectations.
