usually in rap you know the dudes on top are writing their own verses from scratch.
Big, X, Jay, Em, 50, Wayne etc.
maybe even Nelly, Ja..
Dre and Diddy i dont look at them like that.
Ye was the really the first rap superstar who openly had writers but you know he was producing most of his records.
people thought Drake's talent was song writing and crafting catchy songs, if he cant even do that by himself then his competition now becomes Beyonce, Bieber and Rihanna instead of rappers.
