Andrew Powell-Morse, a scientist at Seatsmart, seems to think so.
Using a tool called the Readability Score, Powell-Morse plugged in various songs to find out which genres and artists use a wide vocabulary. In his results he found that Nickelback lyrics require a third-grade reading level, whereas Avenged Sevenfold’s lyrics are closer to a second-grade level.
He analyzed 225 song across various genres, all of which spent at least three weeks at the top of the Billboard charts.
