Is Music Getting Sadder? The Data Says Yes

Music by the Numbers · Meshplugins.com

In the 1960s, most hits sounded happy. Today, more than half are in a minor key — and the data has been trending that way for 60 years.

Researchers scored decades of hits for 'valence' (musical happiness). The trend is remarkably consistent: pop keeps getting moodier.

One analysis of over 9 million tracks (1960–2025) found valence falling across almost every genre. Modern hits are also more emotionally ambiguous — sad-sounding songs set to upbeat tempos, and vice versa.

Why pop turned moody

Theories range from the cultural (a more anxious, ironic era) to the technical (minor keys and darker sounds are easy to reach in a DAW, and streaming rewards mood and vibe over sing-along cheerfulness). Whatever the cause, the minor key is now the sound of the mainstream.

FAQ

Is music actually getting sadder?

By the data, yes. Major-key hits fell from ~85% in the 1960s to ~40% today, and analyses of millions of tracks show valence (musical happiness) declining across almost every genre.

Why do minor keys sound sad?

Minor keys use a lowered third (and often sixth and seventh) that our ears, trained on Western tonality, associate with tension and melancholy.
