Yeah I know what you mean, the way I look at it Drake, next to like likes of Wayne and Birdshit he sounds fucking amazing but half the damn time his verses are a bunch of random ass lines that make no sense together, he has great lyricism but at times wack flow, usually about money or some female. Biggie on the other hand had a rare gift of getting not just verses, but entire songs, hell all of Ready To Die seemed to flow majestically creating arguably the best rap album of all time.
Slick Rick is under-appreciated; second best storyteller of all time next to teh GOAT Pac of course.
