I ain't no backpack rapper, I ain't no lyricist
Many different sects of rappers include the conscious (lyrical) and backpack rappers who might focus on various other things such as wordplay. Jay Rock is none of these, he just speaks what he feels and doesn’t concern himself with falling into categories.
Could also be a shot at Meek Mill. Meek Mill called Kendrick and TDE music for backpack rappers.
