This guidebook is divided into rough "subgenres" of rap music. For the most part, these aren't going to be the subgenres you'd find in other listings. Rather, they categorize the music by its strengths and notable features rather than by its social context. Instead of listing music as, e.g. "southern crunk," it might instead be listed as "poetic." While the traditional labeling schemes are helpful when you're familiar with the genre itself, they're not particularly useful when you don't know what you're looking for.This guidebook is divided into rough "subgenres" of rap music.
