Lack of lyricism
Counterpoint: Waka Flocka Flame’s Flockaveli (2010)
Just because the rapper at hand isn’t super Lupe lyrical doesn’t instantly discount the musical premium. There are great LPs made for nodding in your Beats By Dre ’phones, and then there are knocking albums fit for the whip or the club turn-up. Instead of comparing Project Pat to Rakim, try to understand the purpose of the music at hand and the environment it reflects.
