Researcher at Musixmatch chose eight popular genres and compared the average vocabulary sizes within each. After reviewing over 360 artists and 15,000 songs, it was decided that hip-hop has the highest average vocabulary size, along with the most average words per song. Heavy metal surprisingly took second place, followed by folk and rock music.
Electronic music, on the other hand, was ranked last – the songs are primarily instrumental, so vocabulary is never a heavy focus.
