Summary: A monumental study from the Centre for Digital Music at Queen Mary University of London reveals that popular music lyrics have grown increasingly negative over the past six decades, signaling a profound shift in global cultural values. By deploying advanced artificial intelligence and computational language analysis to scrutinize more than 380,000 songs released between 1960 and 2023, researchers mapped the largest historical dataset of moral content in music to date.
The findings act as a powerful cultural barometer: over the last 60 years, expressions linked to traditional moral virtues like care, decency, and social connection have steadily plummeted. In their place, modern popular music has seen a stark rise in language associated with moral vices, including harm, cheating, subversion, and degradation. This cross-generational evolutionary shift toward darker emotional narratives, anger, and disgust offers unprecedented insight into how contemporary societies communicate identity, collective values, and psychological distress.
Key Facts
- The Virtues Decline: Textual analysis reveals a multi-decade drop in linguistic markers tied to fundamental human virtues such as care, loyalty, and decency.
- The Rise of Vices: Popular lyrics have experienced a sharp, linear escalation in themes of moral vices, explicitly leaning into concepts of harm, cheating, subversion, and societal degradation.
- Emotional Darkening: Accompanying the moral shift is a significant macro-level surge in overall negative sentiment, specifically characterized by heightened expressions of anger and disgust.
- Genre-Driven Narratives: The evolution of moral language is tightly bound to musical style, with certain genres serving as traditional vehicles for community connection, while others emphasize shock-factor, rebellion, and conflict.
- Gender Disparities in Expression: The study noted distinct correlations within attributed artist gender categories. Female artists more frequently utilized language reflecting care and loyalty, whereas male artists and mixed-gender groups were disproportionately tied to themes of harm and subversion.
- Societal Mirror: Because popular music simultaneously reflects and shapes collective human behavior, these hidden linguistic patterns provide a unique diagnostic lens for current debates surrounding global mental wellbeing and social cohesion.

Popular music may be reflecting a growing culture of vices, according to new research from the Centre for Digital Music at Queen Mary University of London. The analysis of musical evolution has found that song lyrics have become increasingly negative over the past six decades, with declining references to moral virtues. This could provide an important indicator of a change of culture in society.
The findings suggest that music may act as a powerful cultural barometer, offering insights into how societies express emotions, values and moral concerns across generations.
After analysing more than 380,000 songs released between 1960 and 2023, researchers discovered a significant shift in the emotional and moral language used in popular music. Expressions associated with moral virtues such as care and decency became less common over time, while language linked to harm, cheating, subversion and degradation increased.
Lead author Dr Vjosa Preniqi, from Queen Mary University of London, said:
“Music is much more than entertainment. It is one of the ways societies tell stories about themselves. By analysing song lyrics across several decades, we can begin to see how emotional expression and moral narratives evolve over time.
What we found was a gradual shift away from language associated with virtues such as care and decency, towards themes that reflect conflict, harm and other moral concerns. These patterns are dependent on various factors, such as genre and shock-factor, but they provide a fascinating window into changing cultural values and emotional expression.”
The study examined two large popular music datasets spanning more than 60 years, making it the first study to chart moral content in song lyrics at this scale: more than 377,000 English-lyrics songs covering 1960 to 2010 were filtered from the WASABI dataset and complemented with 5,500 songs that made Billboard’s year-end charts between 1960 and 2023. Using advanced artificial intelligence and language analysis techniques, the researchers tracked how different moral themes appeared in music over time.
Their analysis revealed a rise in expressions associated with moral vices such as harm, cheating, subversion and degradation, alongside increasing levels of negative sentiment, anger and disgust. At the same time, expressions linked to moral virtues such as care and decency became less prominent.
Senior author Dr Charalampos Saitis, Assistant Professor of digital music processing at Queen Mary University of London and a co-investigator CDT in AI and Music, said:
“Popular music provides a unique lens through which to explore cultural change. Because music is such a widespread and influential form of expression, analysing lyrics at scale allows us to identify patterns that would otherwise remain invisible. Music both reflects and shapes the world around us. Understanding how moral narratives evolve in lyrics can help us better understand wider changes in culture, identity and collective values around important social issues.”
The research also uncovered differences between genres and artist groups, suggesting that moral expression is closely linked to musical style and storytelling traditions. While some genres were more strongly associated with themes of care and social connection, others more frequently expressed conflict, rebellion and darker emotional narratives.
The findings also revealed observed associations between attributed artist gender categories and lyrical moral content, though these should be interpreted in light of the binary artist gender classification and the substantive artist gender imbalance in the datasets. The research found that women artists were more frequently associated with virtues like care and loyalty, while in contrast men and mixed-gender groups more frequently reflected negative themes such as harm, subversion and degradation.
By combining computational methods with theories of morality and human behaviour, the researchers were able to uncover long-term cultural trends hidden within decades of popular music.
As debates around mental wellbeing, social cohesion and cultural change continue, the team believes music offers a valuable record of how societies communicate their emotions, meaning and values.
Key Questions Answered:
A: Music is one of the primary mediums through which human groups share their internal emotional landscapes and tell stories about themselves. When researchers analyze lyrics at a massive scale—spanning hundreds of thousands of songs over 60 years, individual creative choices blend into broader cultural trendlines. A systemic increase in words related to anger, harm, and cheating tells us that the psychological baseline of the listening public and the artists creating the art has actively shifted toward processing stress, conflict, and disillusionment.
A: The team from Queen Mary University of London utilized advanced natural language processing (NLP) algorithms trained on established behavioral and psychological models of human morality. These AI systems read through the massive WASABI and Billboard datasets, tagging and categorizing specific vocabulary words and contextual phrases according to their alignment with moral foundations (like care vs. harm or loyalty vs. subversion). This computational approach uncovers large-scale macro-trends that would be entirely invisible to a human researcher trying to read or listen to thousands of songs manually.
A: Not necessarily. The relationship between music and culture is a feedback loop: music both reflects the world as it currently exists and shapes the values of the generation consuming it. The rising prominence of themes like degradation or subversion could mean that society is becoming more cynical, but it can also indicate that modern artists are using music as an unfiltered, authentic outlet to process complex real-world pressures, such as economic stress, mental health crises, and social fragmentation, that older generations may have swept under the rug due to rigid broadcasting standards.

Abstract
Evolution of moral expression in song lyrics
This study examines the evolution of moral expressions in popular music lyrics over six decades. Using the WASABI dataset (1960-2010) and Billboard year-end charting songs (1960-2023), we analyse temporal trends in moral narratives across artist genders and musical genres.
Transformer-based language models fine-tuned for moral foundation prediction were applied to quantify ten moral dimensions derived from Moral Foundations Theory.
Our findings reveal an increase in moral vices (e.g., Harm, Cheating, Subversion), and a decline in expressions of moral virtues (e.g., Care, Purity), alongside a rise in negative sentiment, anger, and disgust.
We show that moral dimensions can be inferred by lyrical cues, such as thematic content, sentiment, and emotion, with predictive accuracy improving notably when models are trained on specific music genres.
These findings reveal that shifts in lyrical morality co-occur with broader societal changes in values and identity, underscoring how popular music may serve as a cultural barometer for evolving moral norms.
