To fully understand rap, we must first be fluent with its meter, rhyme, and figures of speech. Then ask two questions: One, how artfully has the objective of the song been rendered, and two, how important is that objective. Question one rates the song's perfection, question two rates its importance. And once these questions have been answered, determining a song's greatest becomes a relatively simple matter.

If the song's score for perfection is plotted along the horizontal of a graph, and its importance is plotted on the vertical, then calculating the total area of the song yields the measure of its greatness.
