You’re washing dishes, walking to work, or staring at the ceiling at 2 a.m., and there it is again – that fragment of a song, looping endlessly with no off switch in sight. Most people know exactly what this feels like. An earworm, also described as sticky music or stuck song syndrome, is a catchy or memorable piece of music that continuously occupies a person’s mind even after it is no longer being played or spoken about. It sounds trivial. It often isn’t. Scientists have spent decades trying to understand why these uninvited musical guests refuse to leave, and what they reveal about the deeper architecture of the human brain.
How Common Are Earworms, Really?
Earworms are an extremely common aspect of everyday human experience, regularly affecting somewhere between 72% and 92% of the population. Some estimates go even higher. According to research by James Kellaris, 98% of individuals experience earworms. That makes it one of the most universal cognitive phenomena known to science. It’s not a quirk of certain personality types or music lovers alone – it cuts across nearly all demographics.
A study from the Proceedings of the 10th International Conference on Music Perception and Cognition found that more than 91% of people reported having an earworm at least once a week, while about a quarter had them more than once a day. Women and men experience the phenomenon equally often, but earworms tend to last longer for women and irritate them more. The numbers alone make one thing perfectly clear: this isn’t a niche experience. It’s a fundamental feature of the human mind.
What’s Actually Happening Inside the Brain
Scientists trace earworms to the auditory cortex in the temporal lobe of the brain, which controls how you perceive music, as well as deep temporal lobe areas responsible for retrieving memories. The amygdala and ventral striatum, parts of the brain that involve emotion, also tie into the making of an earworm. This isn’t just one brain region firing on its own – it’s an interconnected network lighting up in a coordinated loop. MRI experiments found that involuntary musical imagery is “a common internal experience recruiting brain networks involved in perception, emotions, memory and spontaneous thoughts,” as a 2015 paper in Consciousness and Cognition reported.
Research shows brain function is broadly similar when people listen to music and when they experience musical imagery like earworms. The word imagery here refers to the imagined nature of the earworm – it is not a sound being heard out loud, it is instead within the mind. But the part of the brain called the auditory association cortex, which handles more complex tasks related to music listening, seems to play a bigger role with musical imagery than the primary auditory cortex. In other words, your brain is doing something more sophisticated than simple playback when an earworm takes hold.
Why the Brain Gets Stuck in the Loop
Involuntary musical imagery is theorized to manifest as a result of the Zeigarnik Effect – a phenomenon where unfinished or interrupted tasks are more easily remembered in comparison to completed tasks. You might find yourself looping a 10-second part of a song rather than the full three-minute track. This is because your brain treats hearing only part of a song as an incomplete or interrupted task. When you don’t finish the song, your brain keeps bringing it back and looping. It’s a memory system doing exactly what it was designed to do – resolve the unfinished – just in an incredibly frustrating way.
Psychologically, earworms are a “cognitive itch”: the brain automatically itches back, resulting in a vicious loop. The more one tries to suppress the songs, the more their impetus increases, a mental process known as ironic process theory. A study of 293 participants confirmed this dynamic directly. Those who attempted to suppress their earworms tended to have more frequent earworms and a higher White Bear Suppression Inventory score, a measure of how often people try to suppress unwanted thoughts. This demonstrated that people who suppress thoughts in general experience more involuntary thoughts overall, which includes earworms.
What Makes a Song Turn Into an Earworm
Not every song gets stuck. There’s a specific recipe for stickiness, and researchers have started to decode it. Earworms are usually faster, with a fairly generic and easy-to-remember melody but with some particular intervals, such as leaps or repetitions that set them apart from the average pop song, according to the first large-scale study of earworms. The research, led by Kelly Jakubowski of Durham University, surveyed 3,000 people on their most frequent earworm tunes. Three melodic features emerged as significant predictors of earworm status: a “common global contour,” meaning the overall shape of the melody was one commonly found in pop music; an “uncommon average gradient at turning points in the melody,” meaning earworms contain steeper rises or falls at points of melodic inflection than is usually found in pop songs; and a faster tempo, with earworms over 9 beats per minute quicker than non-earworms on average.
Kellaris produced statistics suggesting that songs with lyrics may account for 73.7% of earworms, whereas instrumental music may cause only 7.7%. Recent exposure also plays a major role. Research indicates the importance of being repeatedly exposed to music in the development of earworms. Adding further complexity, it seems probable that both the catchiness of a song and people’s exposure to it tend to be mutually reinforcing. The more you hear it, the stickier it becomes – and the stickier it is, the more it gets played.
Earworms, Personality, and Mental Health
Who gets earworms more – and why – turns out to be a fascinating window into broader neurocognitive patterns. In terms of the Big Five personality traits, neuroticism significantly predicted occurrences of earworms. Williamson’s research found that people with neuroticism and non-clinical levels of obsessive compulsion experience earworms more often, and for longer periods of time. “These people tend to have more repeated thought processes in general, so it’s perhaps not a huge surprise that these are reflected in their experiences of mental music as well,” she noted. The connection to habitual thinking patterns runs deeper than just personality.
A major 2025 study published in the journal Consciousness and Cognition explored this further. Participants (N = 883) completed an online survey measuring frequency of earworms, other habits and compulsions, everyday habitual tendencies and anxiety. Habitual tendencies in everyday life positively predicted earworm frequency, control and disturbance, even when controlling for anxiety. Furthermore, earworms were strongly associated with 22 other habitual behaviors and compulsions, with the strongest associations being observed for repetitive motor behaviors such as foot tapping, and repetitive mental behaviors such as counting and spelling. According to the Harvard Medical School, earworms can sometimes occur with obsessive-compulsive disorder, psychotic syndromes, migraine headaches, unusual forms of epilepsy, or a condition known as palinacousis.
How to Actually Get Rid of an Earworm
Suppression, as we’ve established, tends to backfire. So what actually works? Scientists at Western Washington University found that engaging working memory in moderately difficult tasks such as anagrams, puzzles or reading was an effective way of stopping earworms and of reducing their recurrence. The key, according to psychologist Ira Hyman, is finding a cognitive task that hits a Goldilocks zone – not too easy, not too hard, but just challenging enough to fully occupy the relevant mental circuits. These strategies work by activating the component of working memory involved in earworms, a storage and rehearsal cycle called the phonological loop. “If you fill it up with something else that occupies the same circuitry, there’s not enough left to make the earworm,” Victoria Williamson explains.
One of the most surprising and well-supported remedies comes from a study at the University of Reading. An effective solution to get rid of earworms has been found by a team of scientists at the University of Reading, UK. Published in the Quarterly Journal of Experimental Psychology, the results show the best way to block obsessive melodies is neither to read a good novel nor solve complex anagrams but, simply, to chew gum. The act of gum-chewing is very similar to irrelevant sub-vocalisation, which has proved to degrade short-term memory performance as well as auditory images. Auditory images are less vivid when individuals are engaged in tasks loading on their inner voice. There’s also a longer-term approach: instead of trying not to think about it, you deliberately listen to the entire song, start to finish, several times in a row. Most earworms are fragments, which very likely contributes to their stubborn longevity; incomplete memories last longer than complete ones, a phenomenon known as the Zeigarnik effect.
