In the song "Follow the leader" Rakim said "I can go on for days and days with rhyme displays that engrave as deep as x-rays" thats just one of the sick lines that Rakim use to spit i remember seeing him for the first on his video for "I aint no joke " (back in the days of yo!mtv raps! with Ed Lover & Dr. Dre) my jaw dropped and i was like oh my god ,who is this guy Rakim? i gotta get this, and then i was hooked Rakim is the greatest rapper ever,without question in my mind.
