7. Master P "Ghetto D"
"Make crack like this." Few drug-dealing songs are so literal, but "Ghetto D"—off of Master P's groundbreaking 1997 album of the same name—was an attempt to obliterate the boundaries between art and reality, to hew as closely as possibly to transparency. In fact, it was a literal instruction manual for mixing up crack, set to a minimal, gritty backing track. Ironically, it was also a remake of Eric B and Rakim's "Make Em' Clap to This," a re-purposing of hip-hop history in an attempt to eliminate artifice.
