A systematic review and meta-analysis published in 2025 brought together 82 studies on song lyrics and found medium effects on behavior and attitudes, and a large effect on emotion. What is most revealing is not simply that lyrics have an influence, but that their impact tends to align with the message they convey.
For years, we have discussed music’s power to alter mood, lodge in memory, or change a space’s energy. But this study shifts the question to something more subtle: not what music does as sound, but what it leaves within us when it also brings words.
The authors begin with a concrete reality: music consumption today is around three hours a day, popular music dominates much of our listening, and its lyrics often carry narratives about relationships, attraction, possessive love, emotional health, partying, substance use, or social protest.
Seen this way, lyrics cease to be an embellishment and become a form of storytelling that lives alongside us far more than we usually acknowledge.
Key definition: The study by Marín-Liébana and Ibias (2025) followed the PRISMA protocol and combined a systematic review with a meta-analysis to answer this question: if lyrics convey narratives capable of shaping perception, to what extent do they have measurable psychological effects on listeners? (Psychology of Music).
To answer the central question, the researchers brought together 82 studies and 42 dependent variables, then worked with a selected experimental sample to analyze three domains: cognitive-behavioral, emotional, and attitudinal.
The overall picture of the field is already revealing:
Important point: This is neither a vague intuition nor a peripheral discussion. It is a broad, fairly structured body of research centered on the music that circulates most widely in everyday life.
Across the meta-analyses, the estimated effect size was larger in the emotional domain than in the cognitive-behavioral and attitudinal domains. These estimates come from different sets of outcomes, not a direct comparison of all three responses in each listener.
| Domain of impact | Effect size (standardized mean difference) | Interpretation |
|---|---|---|
| Cognitive-behavioral | 0,50 | Medium effect |
| Attitudinal | 0,57 | Medium effect |
| Emotional | 0,81 | Large effect |
These estimates highlight the relevance of emotional responses without establishing a fixed sequence from emotion to attitude to behavior. Before an observable decision, a song may be associated with changes in mood, empathy, or disposition; this does not happen identically in everyone.
The review includes findings related to donations, tips, fair-trade coffee purchases, interest in charitable causes, attention, concentration, verbal reasoning, and performance.
Implicit conclusion: Lyrics do more than accompany; sometimes they compete.
Here the work becomes particularly unsettling. The review summarizes the following:
The underlying pattern: the direction of the effect tended to be consistent with the lyrical content.
The review includes variables such as self-esteem, body image, sexuality, acceptance of violence, prejudice, and discriminatory thinking.
One of the most interesting ideas is that a song does not need to change behavior before our eyes to be psychologically relevant; it is enough to shift the mental framework through which a person interprets what is acceptable, desirable, or normal.
Most valuable of all, the study does not turn these findings into a slogan. It does not suggest that a song automatically controls its listeners or that lyrics work as a direct switch for behavior.
In the emotional domain, heterogeneity was high, with an I² of 74.51%. Results varied across studies, and that variation cannot be conclusively attributed to any single factor. Occasional listening in laboratory settings and immediate measurement also predominated: the findings do not establish permanent changes or automatic applicability to every commercial space.
Strategic conclusion: Lyrics do have an influence, but not mechanically. They influence us because they convey narratives and imagery capable of affecting emotion, attitude, and behavior in measurable ways, particularly in older adolescents and young adults.
Perhaps that is the meta-analysis’s most powerful contribution. It does not invite us to distrust music, but to listen more consciously.
The following proposals are curatorial principles informed by the study. They are not a validated protocol for hotels, restaurants, stores, or events, and they do not guarantee audience responses.
Those of us who work closely with music curation understand that choosing a song is never a completely neutral act. This study offers something better than intuition: it brings method, scale, and evidence.
Ultimately, that is the difference between playing music and designing an experience thoughtfully.
Playing music fills the silence.
Designing thoughtfully means recognizing that every lyric conveys narratives that can affect emotion, attitude, and behavior.
It leaves a question hanging, difficult to ignore: if lyrics can leave so much within us, do we really still believe we were only listening to music?
