your body is trying to fluff up fur you don't have anymore
That wave of tiny bumps down your arm when a song hits just right — your body is trying to fluff up fur you don't have anymore.
The same reflex is triggered by strong emotion / music (frisson, "aesthetic chills"), not only cold and fear.
The exact same system that raises our hairs when it's cold out is fired in response to a beautiful film score.
only the goosebumps response appears to have been objectively captured during engagements with music, film and poetry
feeling or remembering strong and positive emotions ... or while watching a horror film.
UPRIGHT
that muscle yanks the hair upright
Every hair you've got sits on a tiny muscle, and when a nerve fires, that muscle yanks the hair upright.
Goosebumps = arrector-pili muscles contracting, driven by the sympathetic nervous system, pulling hairs upright. Original function in furry ancestors: raised hair traps air for insulation AND makes the animal look bigger to threaten enemies; in near-hairless humans it is considered a vestigial leftover.
The formation of goose bumps in humans under stress is considered by some to be a vestigial reflex.
Your sparse arm hairs, standing at attention in the cold, trap virtually no meaningful layer of insulating air.

your furry ancestors used it to trap warmth and to look bigger to whatever scared them

ANCIENT
Next time a song gives you chills, stop and feel it for a second — that's an ancient reflex in your skin, moved by something beautiful.

“"Goosebumps are completely useless in humans." Overclaim”
Wikipedia hedges the vestigial label ("though visible piloerection is associated with changes in skin temperature in humans"), and recent work links the arrector-pili/nerve unit to hair-follicle regeneration. Script hedges to "in you it barely does anything" — never "useless."
“A specific percentage of people who get music-chills”
Sources range ~38%–70%. No number ships; the script does not quantify.
“Naming the emotion pathway with false precision (dopamine/striatum/amygdala)”
True but more than the wonder-register script needs; kept out of narration, left here as context.
Publishing what we refused to claim is the strongest evidence the rest was checked.
