The Simplification of Song Lyrics: An Analysis of 12,000 English Songs from 1990 to 2020

An analysis of over 12,000 English songs from various genres like rap, country, pop, R&B, and rock from 1990 to 2020 reveals that song lyrics have become simpler and more repetitive over the past four decades. The study published in Scientific Reports highlights the shift in music over the years, noting the changing values, emotions, and concerns reflected in lyrics.

Lead author Eva Zangerle, an expert in music recommendation systems at the University of Innsbruck, emphasizes that lyrics act as a mirror of society, showcasing cultural changes and trends. With the advent of the internet and streaming services, the music industry has undergone significant changes compared to previous decades when music was primarily consumed through vinyl and cassettes. The study examined emotional expression, complexity of words, and repetition in lyrics across genres, noting a trend towards simplification and repetition.

Interestingly, rap music was found to have a more prominent role in using repeated lines and expressing anger compared to other genres. The study also indicated a decline in positive and happy content in lyrics over time. The increasing use of first-person pronouns like “I” and “mine” suggests a more self-centric approach in songwriting. Additionally, the study pointed out the importance of engaging listeners immediately in the streaming era, as songs need to capture attention within the first few seconds to avoid being skipped.

Overall, the study indicates that songs with more repetitive choruses and basic lyrics tend to be more popular in the current music landscape. The changing trends in lyrics reflect the evolving music industry and society’s values and emotions.
