'Reasonable Doubt,' by Jay-Z

Before S. Carter was the king of the ROC, 'Reasonable Doubt' was his crowning achievement. Featuring Mary J. Blige, Biggie, Foxy Brown and Memphis Bleek, and classic production by Clark Kent and DJ Premier, the album introduced young Hov to the world in a truly memorable fashion. His ambition, conscience and braggadocious wit created true masterpiece, and tracks like 'Dead Presidents II,' 'Feelin' It' and 'Brooklyn's Finest' will forever belong in hip-hop's canon.
