They are lyrical wordsmiths, but who boasts the most tools?
This fantastic poster, featuring 100 hand-drawn rapper icons, attempts to sort the wheat from the chaff, with MCs ranked in order of the number of unique words used in each artist's first 35,000 words - roughly equivalent to 3.5 albums.
Naturally, the different rappers are colour-coded - so you can see who's winning the lyrical West Coast/East Coast battle - whisper it quietly but we think the Easties might currently have the edge.
