#18 Scarface - Mr.Scarface Is Back (1991)

Everything Biggie did, everything 'Pac did, everything Jay-Z does was originally done on the first Scarface album. Biggie kills himself at the end of his first record; well, Scarface did it three years earlier. He was the first guy to do his rhymes in the first person about robbing people and drug dealing; he was the first guy to really talk about being depressed and being institutionalized, and how his mama is scared of him. He is the most underrated rapper of all time and absolutely in the top three. You cannot get to four without mentioning Scarface. Any rapper knows that.
