Music relieves pain through real neural mechanisms, but you have to like the song
Scientists confirmed with ice-bucket tests that music you like makes your brain release endogenous opioids comparable to morphine to raise pain thresholds, while music you hate only releases cortisol and makes you more tense.

Music activates more brain regions than any other stimulus
Levitin says music activates more brain areas than anything they've studied, touching nearly every mapped region. Millions of neurons sync with the beat while driving physical movement. The visual cortex lights up—Sting showed unusual visual activity in brain scans while composing, explaining he "sees" music as architecture with floors, arches and buttresses. Levitin himself has aphantasia and forms no visual images when listening to music.
— Dan LevitinMusic switches the brain into legitimate rest mode
Listening shifts the brain into the default mode network—the state activated during mind-wandering and daydreaming, opposite to the focused central executive network. Extended focus depletes neural resources, and genuine recovery comes not from scrolling Facebook but from walking, napping, or listening to music, which resets brain function and replenishes oxygen and glucose consumed by focus. Levitin himself closes his eyes and listens to a few minutes of music to recover when his work focus drops, rather than reaching for coffee.

Levitin's lab created pain by having people hold their hands in ice-water buckets—most can't last more than one or two minutes no matter the reward. When recordings of music the subjects liked were played, they could hold out longer in the ice—music raised the pain threshold, acting like an analgesic. His lab was first to prove the mechanism: liking music causes the brain to release endogenous opioids, the same class of substance as morphine, OxyContin, and codeine, just synthesized by your own brain.
— Dan LevitinDisliked music only makes people more tense
If the music played was something you hate, the effect reverses completely: no pain-relieving endorphins are released; instead the stress hormone cortisol releases, making you more easily distracted and impairing rational thought, plus adrenaline releases making you anxious. Levitin mentions a case: when the U.S. military besieged Panamanian dictator Noriega, they blasted Van Halen continuously, finally forcing him out of his embassy hideout—he hadn't surrendered when water, air conditioning, and food were cut off, but the music drove him to surrender. He acknowledges though that music's pain-relief effect is measurable but nowhere near pharmaceutical strength.

Memory has a principle: information stored first erases last. Most people begin attending to music and forming taste around ages 10 to 12, so those memories persist longest in Alzheimer's. Tony Bennett developed Alzheimer's but can still sing nearly his entire repertoire, even though he can't remember what day it is and will sing the same song three times without knowing. Levitin says when care facilities play residents' youth music for just 20 minutes, they speak again, pulled back from confusion for about a week.
— Dan LevitinMetronomes can't do what music does for Parkinson's walking
Parkinson's degrades the basal ganglia that maintain smooth continuous movement, causing patients to suddenly "freeze" and stop walking. But when music matching the patient's natural step pace is played, they sync with the beat in about four seconds and can walk following the rhythm—this doesn't repair the damaged basal ganglia but provides the motor system an alternative "clock" to borrow. Training is 15 minutes of music walking daily; after weeks of practice, patients can even walk independently without music for a time. A plain metronome doesn't achieve the same effect because it lacks the pull of music to engage the whole brain.
— Dan LevitinThe Mozart effect is proven to be poor experimental design
Levitin calls the widespread claim that "listening to Mozart makes you smarter" complete nonsense, saying the original research was poorly controlled. The original experiment used paper-folding tasks to measure "getting smarter," but whether folding paper represents intelligence is questionable; more critically, the control group sat in a dark room doing nothing, so the result wasn't that Mozart made people smarter but that sitting bored made people temporarily stupid, fatigued, or completely unmotivated to fold paper. He stresses the effect of music never depends on it being classical; it depends on whether you personally like it.
— Dan LevitinFetuses hear music in the womb; infants remember it after birth
The fetal auditory system fully develops around 20 weeks of pregnancy, and amniotic fluid filters sound like bathwater, leaving only bass, beat, and rhythm. Levitin mentions colleague Alexandra Lamont's experiment: a song was played to pregnant women at weeks 20 to 24; over a year later, when the same child heard both the original song and another song by the same artist they'd never heard, the infant showed clear preference for the one they'd heard before. Another ultrasound study found that when a speaker was placed in the pregnant woman's vagina playing music, the fetus showed more mouth movements than when the speaker was on the belly.

When we drift into that mode, if we allow ourselves to go there, it can effectively hit a reset button in the brain and restore neural function and restore the oxygenated glucose that was spent by paying attention.

my lab was the first to show that when you listen to music, it releases opioids in your brain, what we call endogenous, interior opioids, same as you would get in morphine or an Oxycontin or a codeine tablet, but they're in your brain.
Dan Levitin12:32
That not only doesn't release the painkillers, it releases cortisol, which is the stress hormone that makes you more sensitive to distraction and it slows down critical thinking. It releases adrenaline. It upsets you.
Dan Levitin12:32
Well, it's what drove Manuel Noriega out of his compound in Panama. Music he didn't like.
Dan Levitin13:32
If you put on recent music, that means nothing. But if you put on music from their teen years, it allows them to reconnect with the self they thought they had lost.
Dan Levitin18:13
Yeah, this is balderdash. This is just – this was bad science. There was one very poorly conducted study done that purported to show that if you just listen to Mozart 20 minutes a day, you don't need to read books or do math or do anything else because that makes you smarter.
Dan Levitin24:27
So it's not that Mozart made you smarter. Sitting in a dimly lit room doing nothing made you stupider temporarily.

How to listen
For anyone interested in music neuroscience, rehabilitation medicine, or how music can support treatment of Parkinson's and Alzheimer's.
The debunking of the Mozart effect and the fetal music listening experiment are anecdotal and can be skipped.
