Every rapper isn't present but it's pretty broad in who is included. And lol Uzi.

Some of the newer artists wield a smaller vocabulary comparatively, but this is not because hip hop has "dumbed down." The genre has evolved; it has moved away from complex lyricism toward elements traditionally associated with pop music: repetitive song structure and singing (Joe Carmanica recently wrote about this trend for the New York Times, arguing that it was led by Drake, who popularized the rapping-and-singing formula over the past decade).
A better benchmark for Lil Uzi Vert's word count (2,556) might be those of pop artists, such as Beyonce (2,433 words), or even one his major influences: Marilyn Manson (2,466 words).
There are also genre-bending artists. If Childish Gambino's Awaken, My Love! is less hip hop in the traditional '90s boom-bap sense, is it fair to compare it to vocabulary-dense Wu-Tang albums? Genre matters in vocabulary calculations—check out the chart below, which takes 500 random samples of 35,000 words from rock, country, and hip hop.
