I belong to a generation that screamed singing Queen songsLast in line or Extrememoduro that they sounded on a cassette. Therefore, it has not gone unnoticed by me that, in the last five decades, music has changed. The letters they have become simplermore repetitive and loaded with negative emotions or stress.
This shows it a data analysis about more than 20,000 songs that occupied the Billboard Hot 100 between 1973 and 2023 published in the magazine Scientific Reports. This phenomenon does not just happen. In reality, it is our own reflection, and the result of profound social transformations, of how we feel, consume and live our lives.
A study that traces an underlying trend. He study Conducted by researchers at the University of Vienna, it has analyzed the lyrics of popular American songs over a period of five decades, measuring three key variables: presence of stress-related vocabulary, general emotional tone (positivity or negativity) and lyrical complexity based on repetition metrics and word variety.
The result has led researchers to be able to affirm that, from the seventies to today, the use of words associated with stress has increased, the proportion of positive expressions has fallen and the structures of the letters have been simplified.
What does it mean that they are “simpler”? According what was published by Forbesthis pattern is also seen in other investigations that compare songs from different genres over the years and their conclusions are the same: the lyrics of current songs tend to repeat more simple phrases, express intense emotions (such as anger or sadness) directly, and use fewer metaphors or complex images than in the past.
Saying that the songs are simpler does not only mean that they are easy to remember, but that their lexicon and structure have been losing richness and complexity. Bob Dylan won the Nobel Prize in Literature in 2016 “for having created new poetic expressions within the great tradition of American song.” With all the respects to Bad Bunnybut I don’t see him as a candidate for the 2026 Nobel Prize due to the depth of his lyrics.
The algorithm enjoys it. In technical terms, letters that are repeated frequently and use less distinctive vocabulary are more “comprehensible” for algorithms that measure textual complexity. Not only does this make it easier for them to stick in the listener’s head (raise your hand if you’ve never woken up with a catchy song in your head), but it also responds to how we consume music today. In times of streaming and algorithmic listscatchy and repetitive themes compete better for attention.
The change in music has occurred in parallel with the rise of rapid consumption platforms and more fragmented forms of listening. The artists they don’t even play it anymore releasing a good album. Not even with a single, but they compete in a context where the first chorus decides whether the listener continues or skips to the next song. That competition for attention It explains the rise of simple structures and quick hooks, but it also influences the type of emotions that predominate in the lyrics.
A mirror of our collective anxiety. According to the conclusions of the University of Vienna study, the greater presence of terms associated with stress, anxiety or conflict is correlated with emotional state of society. As diagnoses of anxiety and depression increased in the population, an increase in negative language in cultural works has also been detected. This does not mean that music causes these states, but rather that it turns them into a space of expression.
As and as I emphasized Patricia L. Sabbatella, professor of music at the University of Cádiz, “Music is part of everyday life, fulfilling different uses and functions ranging from entertainment, social cohesion, communication, emotional expression and regulation to learning, relaxation or entertainment.” Therefore, this transformation responds to the function of music as a barometer and emotional regulator of society. It is his reflection and at the same time his therapy..
“Surprisingly, social shocks like COVID-19 coincided with attenuations rather than amplifications of these trends, indicating a preference for emotion-incongruent music,” the researchers noted.
What music tells us about ourselves. Although the average negativity and stress has increased, it does not mean that all music is gloomy or empty of meaning. There are artists and songs that challenge these trends. What the study indicates is the dominant pattern, not that all music is like this.
One of the conclusions of the study is that if popular songs are now, in general, simpler, negative and stressful, it is because this phenomenon appears as a reflection of societies with accelerated rhythms, high levels of anxiety and a relationship with digital culture that favors the immediate and emotionally intense. Music is not the cause, but it is a sensitive mirror of how we feel and how we communicate.
In that sense, understanding these changes not only helps explain why a hit from the seventies sounds different from the current onebut also what kind of roles music plays today.
