Earworm

That Song You Can't Escape

Right now, somewhere in the world, millions of people are being tormented by the same few bars of a pop song they heard three days ago. Lady Gaga's "Bad Romance" is probably stuck in someone's head as you read this. So is "Can't Get You Out of My Head" by Kylie Minogue—a song whose title is practically a confession of what it does to listeners.

This phenomenon has a name: the earworm.

The term is borrowed from German, where "Ohrwurm" literally means "ear worm"—as if a tiny creature had crawled into your ear canal and taken up residence in your brain, playing the same melody on loop. The English version first appeared in Desmond Bagley's 1978 thriller novel Flyaway, and the word has been crawling through our vocabulary ever since.

What's Actually Happening in Your Brain

Scientists have a more clinical name for this: Involuntary Musical Imagery, or INMI. It's exactly what it sounds like—music that plays in your mind without you choosing to think about it. Your brain becomes a jukebox with a broken shuffle button, stuck on the same track.

But here's the fascinating part: earworms aren't the same as musical hallucinations. With an earworm, you know the music isn't real. You're not hearing it with your ears; you're experiencing it as a kind of mental echo. True auditory hallucinations—where people actually perceive sounds that aren't there—can result from damage to the temporal lobe, the part of the brain that processes sound. That's a medical condition called palinacousis. Earworms are something else entirely: a quirk of normal cognition that nearly everyone experiences.

How common are they? According to researcher James Kellaris, 98% of people have experienced earworms. You're almost certainly one of them.

The Anatomy of a Catchy Tune

Not every song becomes an earworm. There's a recipe.

In 2016, Kelly Jakubowski and her colleagues at Durham University identified the key ingredients. Earworm songs typically have a fast tempo—they move along quickly enough to stick in your memory. They have simple, easy-to-remember melodies. But there's a twist: the most persistent earworms also contain something unusual. An unexpected interval between notes. A surprising repetition. Something that makes your brain perk up and pay attention.

Think of it like a hook in fishing. The melody needs to be smooth enough to slip into your consciousness, but it needs a barb to keep it there.

The chorus is the most common culprit. That's the part of the song designed to be memorable, the part the songwriter wants you to sing along with. Mission accomplished—sometimes too well.

Radio play matters too. The songs that become earworms tend to be the ones you've heard repeatedly, the chart-toppers that play in every store, every gym, every car driving past with the windows down. Exposure breeds familiarity, and familiarity breeds that maddening loop in your head.

The Usual Suspects

When Jakubowski's research team asked people which songs plagued them most, a familiar roster emerged:

"Bad Romance" by Lady Gaga
"Can't Get You Out of My Head" by Kylie Minogue
"Don't Stop Believin'" by Journey
"Somebody That I Used to Know" by Gotye
"Moves Like Jagger" by Maroon 5
"California Gurls" by Katy Perry
"Bohemian Rhapsody" by Queen
"Poker Face" by Lady Gaga

Lady Gaga appears three times on that list. Whatever she's doing in her songwriting process, it's working—perhaps too well.

The Gender Gap in Mental Jukeboxes

Here's something curious: men and women experience earworms at roughly the same rate, but women report that their earworms last longer and irritate them more. The research doesn't fully explain why. Perhaps women are more attuned to their internal mental states. Perhaps the songs that become earworms are somehow more grating to female listeners. The phenomenon remains somewhat mysterious.

What's clearer is that songs with lyrics account for about 74% of earworms, while purely instrumental music causes less than 8%. Words seem to give the worm extra grip. You're not just remembering a melody; you're remembering language, and language engages different parts of the brain.

Short Loops, Big Annoyance

Research published in the British Journal of Psychology in 2010 found that most earworms are remarkably brief—typically between 15 and 30 seconds of music, playing on repeat. You rarely get stuck on an entire song. Instead, it's a fragment, usually the catchiest fragment, cycling endlessly.

This makes a certain kind of sense. Your working memory—the mental workspace where you hold information temporarily—has limited capacity. A 30-second clip is about the right size to fit comfortably in that space and spin around without interruption.

Musicians tend to experience more earworms than non-musicians. This isn't because music training makes you more susceptible; it's probably because people who love music spend more time listening to it, and exposure is one of the key triggers. The more songs you put into your head, the more ammunition your brain has for involuntary replay.

Happy Songs, Sad Songs, and What They Do to You

You might assume that upbeat songs would be more likely to become earworms—after all, they're designed to be catchy and fun. Researcher Ella Moeck tested this assumption using only instrumental music to eliminate the variable of lyrics.

The results were surprising. Participants experienced roughly equal numbers of earworms from positively-valenced music (happy, calm pieces) and negatively-valenced music (angry, sad pieces). The emotional tone of the music didn't affect how often it got stuck.

But there was a difference in quality. Earworms from sad or angry music caused more distress. They were less pleasant to experience, even though they occurred just as often. Having a cheerful tune stuck in your head is one thing; having a melancholic or agitated one is quite another.

How to Evict the Worm

If earworms are so universal, surely someone has figured out how to get rid of them. Scientists have investigated.

Researchers at Western Washington University found that engaging your working memory in moderately challenging tasks—anagrams, puzzles, reading something that requires focus—can help dislodge an earworm. The theory is simple: your working memory can only hold so much. Fill it with something else, and there's no room left for the unwanted song.

The key word is "moderately" challenging. Tasks that are too easy don't occupy enough mental bandwidth. Tasks that are too hard might frustrate you into distraction, letting the earworm creep back in.

Another approach comes from the University of Reading: chewing gum. This sounds absurd, but there's logic to it. When you experience an earworm, part of what's happening is "sub-vocal rehearsal"—you're essentially singing the song silently to yourself, using the same mental machinery you'd use to actually vocalize. Chewing gum interferes with this process. Your mouth is busy doing something else, which disrupts the silent singing.

Some people swear by "cure songs"—different tunes that can push the earworm out. "God Save the King" (or Queen, depending on the monarch) has been cited as particularly effective in British research. "Happy Birthday" is another popular choice. The idea is to replace one sticky tune with another, preferably one that's less annoying or easier to shake off.

There's also a counterintuitive solution: listen to the entire song. Since earworms are usually just fragments—snippets stuck on repeat—playing the full track from beginning to end can give your brain closure. The loop breaks when the song reaches its natural conclusion.

When Earworms Become Art

Writers have been fascinated by earworms long before scientists started studying them.

Mark Twain published a story called "A Literary Nightmare" in 1876—also known as "Punch, Brothers, Punch"—about a jingle so persistent that the only way to get rid of it was to transfer it to someone else, like passing a virus. The story captured something real about how earworms seem contagious, how you can "infect" another person just by humming a tune.

Science fiction writers took the concept further. Henry Kuttner's 1943 story "Nothing but Gingerbread Left" imagined a song engineered to damage the Nazi war effort—a weaponized earworm so powerful it rendered Adolf Hitler unable to finish a speech. Alfred Bester's 1953 novel The Demolished Man featured a protagonist who used an irritating jingle as mental armor against telepaths. The song was so obnoxious that mind readers couldn't penetrate past it.

Arthur C. Clarke's 1957 story "The Ultimate Melody" presented the darkest vision: a scientist who discovers the perfect melody, one so perfectly tuned to the brain's electrical rhythms that it overwhelms all other thought. The listener becomes catatonic, trapped forever in a single song. The researcher becomes his own first—and last—victim.

Real-Life Obsession

Fiction mirrors reality more closely than you might think.

Jean Harris, who became infamous for murdering Dr. Herman Tarnower in 1980, was obsessed with the song "Put the Blame on Mame" from the 1946 film Gilda. She reported that the song played in her head continuously for over 33 years. She could hold a conversation while the tune ran in the background of her mind, a permanent soundtrack to her life.

Mountaineer Joe Simpson described a different kind of earworm in his 1988 book Touching the Void. After a catastrophic fall in the Peruvian Andes left him badly injured and alone, he crawled for days through glacial terrain. During his semi-delirious struggle for survival, he couldn't get "Brown Girl in the Ring" by Boney M out of his head. Of all the songs to accompany a near-death experience, his brain chose a 1970s disco hit. He wasn't even sure if he was imagining it or somehow actually hearing it.

Who Gets Earworms Most?

Researchers Kazumasa Negishi and Takahiro Sekiguchi investigated whether certain personality types are more prone to earworms. They assessed participants on obsessive-compulsive tendencies, the "Big Five" personality traits (openness, conscientiousness, extraversion, agreeableness, and neuroticism), and musical expertise.

Some obsessive-compulsive traits correlated with earworm frequency—specifically, intrusive thoughts, which makes intuitive sense. If your brain tends to generate unwanted thoughts in general, unwanted songs are probably part of the package. Interestingly, other OCD-related behaviors like compulsive handwashing showed no connection to earworms.

Among the Big Five traits, neuroticism was the strongest predictor. People who score high on neuroticism tend to experience more anxiety, worry, and emotional instability. They also tend to experience more earworms. The music gets in, and it's harder to get out.

Musical expertise had a subtler effect. Trained musicians did experience earworms, but their experience was more "sophisticated"—they might notice different aspects of the stuck music, or experience it with more nuance. Expertise doesn't protect you; it just changes the texture of the experience.

Measuring the Unmeasurable

Scientists now have a formal tool for studying earworms: the Involuntary Musical Imagery Scale, developed by George Floridou, Victoria Williamson, and Daniel Müllensiefen. It measures four dimensions of the experience.

First, "Negative Valence"—how unpleasant the earworm feels. Not all earworms are created equal; some are minor nuisances, while others are genuinely distressing.

Second, "Movement"—whether the earworm triggers physical responses like humming, tapping, or dancing. Many people find themselves unconsciously bobbing along to the song in their head.

Third, "Personal Reflections"—whether the earworm connects to personal thoughts or memories that aren't directly related to the music itself. A song from your wedding might trigger entirely different associations than a song from a commercial.

Fourth, "Help"—whether the earworm serves any useful purpose. This might seem strange, but some people report that background music in their mind helps them focus or regulates their mood. The earworm isn't always a pest; sometimes it's a companion.

Designing for Ten Thousand Years

In 2014, the musician Emperor X released a song with an extraordinary purpose: "10,000-Year Earworm to Discourage Settlement Near Nuclear Waste Repositories (Don't Change Color, Kitty)."

The song was part of a serious scientific discussion about nuclear semiotics—the challenge of communicating danger across millennia. Nuclear waste remains hazardous for tens of thousands of years. How do you warn future civilizations not to dig in certain places when you have no idea what languages they'll speak or what symbols they'll understand?

One proposal, nicknamed the "ray cat" solution, suggested genetically engineering cats to change color when exposed to radiation, then embedding warnings about color-changing cats into folklore and song. If the story is catchy enough, it might survive in oral tradition long after all written records are gone.

Emperor X tried to write that song—a melody so sticky it could survive ten thousand years of earworm transmission, passing from brain to brain across centuries.

Whether it will work, of course, no one alive today will ever know.

The Paradox of the Catchy Song

There's something almost poignant about earworms. We live in an age of infinite music—streaming services with millions of songs, new releases every second. Yet our brains seem to operate on a different logic, latching onto fragments and replaying them far beyond any reasonable limit.

The same mechanisms that allow us to remember music at all—to carry songs in our heads, to recognize a melody from decades ago—are the mechanisms that sometimes trap us in loops. The earworm is not a bug in human cognition. It's a feature that occasionally misfires.

And perhaps there's comfort in knowing that when "Bad Romance" is stuck in your head at 3 AM, you're sharing that experience with millions of other people across the planet. Lady Gaga's little hooks are swimming through all of our minds, connecting us in a strange, involuntary chorus.

Ra ra ah-ah-ah.

You're welcome.
