Song lyrics have increasingly focused on themes of cheating, betrayal, and conflict over the past 60 years, shifting away from earlier emphasis on friendship, loyalty, and mutual support, according to a study by Queen Mary University of London.
The research, which analyzed over 380,000 songs released between 1960 and 2023, utilized artificial intelligence and language analysis to track the evolution of moral themes in music. Findings published in the journal Scientific Reports indicate a general increase in expressions of moral vices such as harm, cheating, subversion, and degradation, alongside a decline in virtues like care and purity.
This trend, extending into the 2020s, highlights a growing prominence of vice-oriented and emotionally charged expressions in mainstream lyrics. Researchers suggest that song lyrics serve as a powerful cultural barometer, offering insights into societal values and emotional expression across generations.
Evolution of Lyrical Themes
In the 1960s and 1970s, popular songs often centered on themes found in tracks like Bill Withers' "Lean On Me" and Ben E. King's "Stand by Me." These songs celebrated friendship, loyalty, and devotion.
More recent hits, however, frequently explore darker emotions and relationships. Examples include Taylor Swift's "Bad Blood" and Eminem's "Love the Way You Lie," which delve into betrayal, conflict, toxic relationships, anger, and hurt.
The study noted variations based on artist gender. Female artists were more frequently associated with themes of care and relationship conflicts such as loyalty and betrayal. Conversely, male and mixed-gender groups more often featured negative themes like harm, subversion, and degradation.
Genre also played a role, with lyrics expressing harm and degradation being most prevalent in metal music. R&B and soul music were most likely to contain themes of care, while purity was most commonly found in religious music.
Cultural Indicators and Broader Trends
Lead author Dr. Vjosa Preniqi stated that music provides a way for societies to tell their stories and that evolving lyrical narratives offer a window into changing cultural values. Senior author Dr. Charalampos Saitis added that popular music offers a unique lens for exploring cultural change, reflecting and shaping the world around us.
The findings align with a separate, recent study from the University of Vienna, which found that song lyrics have become simpler and more negative over the last 50 years, with an increase in stress-related words like "bad," "wrong," and "pain" since the 1970s. This coincided with shifts from more upbeat music of the 1970s and 1980s to more recent negative songs.
