Song: "I Know You Got Soul" (1987)
Album: Paid In Full

Rakim must have owned the fastest watch in the world when he wrote this one, as it really hadn't been all that long since he had dropped a "strong rhyme to step to." The line lives on in infamy, as a brilliant introduction, and as a snap on everyone else. It became one of hip-hop's most-quoted lines (so much so that for many listeners, they first heard it from someone else) because it's ultimately so useful; can you think of a more elegant way to announce your return than a heartfelt apology that's also a slap in the face to everyone else? Neither could anybody else.
