Rap songs are famous for their double entendres, clever turns of phrase, and general ingenuity, but that doesn't mean things always make sense the first time around. Enter Understand Rap, a very funny pop-cultural reference book based on the website of the same name, which precisely explains the confusing lyrics and terms used in rap songs using language that even the most un-hip person can understand. The juxtaposition of a dry, academic tone with hip-hop terminology results in a book that's as entertaining as it is informative.
