Music lyrics have become more repetitive since the 1980s, study says

(CNN) – Music lyrics have gotten simpler, angrier and more repetitive, according to a new study.

Researchers compared English-language rap, pop, country, rock and R&B songs from the 1980s to 2020.

They found the more recently released songs are more repetitive and emotional.

Songs use more rhyming lines, more chorus and more anger-related words.

The study also looked at which music genres people liked to look up lyrics for.

Fans of rap and R&B showed the most interest in song lyrics.

The study was published Thursday in Scientific Reports.
