Rap’s history has been traced many ways — through books, documentaries, official compilations, DJ mixes, university archives, even parties. But until now you haven’t been able to look at the development of the genre through its building blocks: the actual words used by emcees.
We introduce Rap Stats, a tool to plot the frequency of words appearing in rap songs from 1988 through the present day. You can use Rap Stats to perform your own searches at http://rapgenius.com/rapstats
No idea how accurate these charts are but check the slideshow for a few words that I looked up. Comment on interesting charts you have created.
