Half of the rappers you named are lucky to have 3 albums to their name. Mase? "Everyone" from Rocafella? Take out Dre and Kanye because the vast majority of their best songs/beats have been their own
We're not talking discography, we're talking production. And YES Mase, his albums are all at worst good albums, with good to great production.
Everyone on the Roc was getting prime Just Blaze, Kanye, Swizz, just to name a few. And why does Kanye and Dre producing for themselves disqualify them from the conversation?
Besides Mase and the role players on the Roc everyone on my list has over 3 albums. And Mase's 3 albums all have great production, and the role players on the Roc/State Prop I'm counting as a whole, and altogether they have more than 3 albums (Tough Love, Brothers From Another, Philadelphia Freeway, State Prop 1 & 2, plus countless mixtapes--from their ties to Jay and Kanye they had incredible production nonstop.)
Again u can't just remove Kanye and Dre cause they produced for themselves that's nonsense based on nothing more than u moving the goalposts to strengthen ur argument.
And besides the solo State Prop acts who don't have 3 solo albums, who did I list that is LUCKY to have 3 albums? If u say Beanie youre probably young. He has 3 good to great albums filled with great production, and a handful of mixtapes that rival most rappers best albums.
Fab and Ross earned the right to drop pretty much whenever they want, and they both have very good/great to amazing production everytime, and I damn near hate Ross and haven't fukked with Fab like that in years. Snoop's legacy was sealed in the 90s and had great production then.
Nas is my 2nd GOAT, but his production is his weakest link by far. Still good to great production just not on par with his abilities as a rapper/lyricist.
