A six-decade study of pop lyrics finds care and decency fading, harm and contempt rising. The charts may be telling us less about music than about ourselves.
Out of the abundance of the heart, the mouth speaks.
Luke 6:45
Researchers at Queen Mary University of London ran 380,000 songs through a moral-language model and watched six decades tilt: words for care and decency thinning out, words for harm, cheating, and contempt creeping up. The easy reading is that music got worse. The honest reading is harder. The charts are not a verdict; the genre mix that dominates them has changed enormously since 1960, and the past was never as clean as nostalgia remembers.
Still, the old line about the mouth speaking from the heart's overflow assumes what the study merely counted. A song is what a crowd already half-believes, set to a beat it will hum until it believes it more. What a people puts in its music is partly a confession of what it loves and partly a rehearsal of what it is becoming. The interesting question was never whether the songs changed. It is what they have been practicing in us.
