It’s always fun to see what creative things people can do with a little bit of data and some statistical analysis.  Designer and data scientist Matt Daniels analyzed the first 35,000 lyrics in the official works of more than 80 rap and hip hop artists and groups, and sorted them by who has the most extensive vocabularies.  The data analysis may not be perfect — I’m not sure I approve of counting variations of the same word as distinct from each other — but the picture that emerges is quite entertaining.  Check it out here, but be forewarned:  this is an analysis of rap and hip hop music, so there is some strong language on this site.
