In rap, as in most popular lyrics, a very low standard is set for rhyme; but this was not always the case with popular music.

This is what rhyme does. In a couplet, the first rhyme is like a question to which the second rhyme is an answer. The first rhyme leaves something in the air, some unanswered business. In most quatrains, space is created between the rhyme that poses the question and the rhyme that gives the answer - it is like a pleasure deferred.

Great poetry does not have to be technically intricate.
