I'm glad someone posted this song, cause of death is another good one by him, caught in a hustle, dance with the devil (not really a life lesson in there but this song will make you say god damn), Harlem streets as well.
People under the stairs - acid rain drops (good positive message)
Dead Prez - They' schools, police state, animal in man (amazing concept), list goes on
Lupe - dumb it down, little weapon, the die (notice the sarcasm)
edit: Jedi Mind Tricks - uncommon valor
**** it I'm done, not like anyone's even gonna listen.
