Story highlights Four rappers top the list, followed by Bob Dylan

The study examined 93 top-selling artists across 25 genres

(CNN) Music artists Eminem, Kanye West and Bob Dylan have something surprising in common.

According to a new study , the trio are among the top five artists with the largest vocabularies in the music industry.

Varun Jewalikar and Nishant Verma, who put the report together for the lyrics site Musixmatch, looked at 93 artists across 25 genres from pop to new age.

"The aim is to compare the vocabulary size of these musicians," they say in the study. "Some of them have released a lot more songs than the others because of the sheer longevity of their career and how prolific they are."

Using a list of 99 of the best-selling artists of all time, the pair compared "across the 100 densest songs (by total number of words) that they have released." However, the analysis excluded Bruce Springsteen, Chicago, Def Leppard, Journey, The Beach Boys and The Doors because they haven't granted permission for Musixmatch to use their lyrics.
