This poll is missing
Undun- The Roots
American Gangster- Jay-Z
Prince Paul- Prince Among Thieves
Childish Gambino- Because The Internet
But amongst every album included in the poll I voted Good Kid M.a.a.d City with honorable mention to The Cool.
Only reason I didn't pick Cool over GKMC is because more of GKMC's songs followed the storyline while Lupe spread the main story of The Cool out amongst 6 songs on that album (and rather briliantly across 3 albums and 2 mixtapes)
