You know that feeling. You’re brushing your teeth or maybe staring at a spreadsheet, and suddenly, a three-second loop of a melody starts runnin through my head without an invitation. It’s relentless. It’s usually a song you don’t even like. Maybe it’s a commercial jingle from 1998 or a fragment of a Dua Lipa bridge. Scientists actually have a name for this: Involuntary Musical Imagery (INMI). Most of us just call them earworms.
It’s annoying.
Honestly, it’s more than just annoying for some people. It can be a genuine distraction that keeps you up at night or breaks your focus during an important meeting. But why does the brain do this? Why does it latch onto "Who Let the Dogs Out" when you’d much rather be thinking about literally anything else? It turns out, our brains are hardwired for pattern recognition, and music is the ultimate pattern.
The Mechanics of a Brain on Repeat
The phenomenon of music runnin through my head isn’t some weird glitch. It’s actually a byproduct of how we process information. When you hear a song, your auditory cortex lights up. But research from institutions like Goldsmiths, University of London, suggests that when the music stops, the brain continues to "play" the track to fill the silence. It’s a bit like an echo in a canyon that refuses to fade out.
Dr. Vicky Williamson, a leading expert on the psychology of music, has spent years cataloging why certain songs stick. Her research indicates that "earworminess" (not a technical term, but let's go with it) often comes down to a mix of simple melodic structures and rhythmic repetition. If a song has a predictable interval—like the leap in "Somewhere Over the Rainbow"—it’s more likely to get stuck.
Sometimes it’s about triggers.
You might see a specific brand of cereal, and suddenly a jingle starts runnin through my head because your brain associated that visual cue with a sound years ago. It’s a neural shortcut. We don't always realize we're being triggered, which makes the experience feel spontaneous and, frankly, a bit spooky.

Why Some Songs Are "Stickier" Than Others
Researchers at the University of St Andrews actually tried to create a mathematical formula for the perfect earworm. They looked at five key factors: receptivity, predictability, melodic variation, rhythmic repetition, and "potency." Essentially, a song needs to be simple enough to remember but just "weird" enough to catch the brain’s attention.
Think about Lady Gaga’s "Bad Romance."
The "Rah-rah-ah-ah-ah" part is a masterclass in sticky songwriting. It’s repetitive. It’s rhythmic. It’s easy to mimic. When that starts runnin through my head, it’s because the brain finds that specific phonetic loop incredibly easy to replicate in the internal monologue.
There's also the "Zeigarnik Effect" to consider. This is a psychological concept where people remember uncompleted or interrupted tasks better than completed ones. If you only hear a fragment of a song on the radio before jumping out of the car, your brain might keep it runnin through my head because it wants to "finish" the loop. It’s seeking closure that it never got.
The Role of Stress and Boredom
It’s not just about the music. It’s about you.
Studies show that earworms happen most frequently when the brain is in a "low-attention" state. This means when you’re doing something repetitive—like folding laundry or jogging—your mind has surplus energy. It uses that energy to replay music. On the flip side, high stress can also trigger it. If you’re anxious, your brain might default to a familiar melody as a sort of "defensive" mechanism to self-soothe, even if the song itself is irritating.

How to Stop the Loop
If you’ve had a track runnin through my head for three hours and you’re losing your mind, there are actually science-backed ways to kill the vibe.
Chew some gum. This sounds ridiculous, but it works. A study published in the Quarterly Journal of Experimental Psychology found that the act of chewing interferes with the "inner voice" we use to imagine music. Since you use the same motor pathways for speech and sub-vocalizing music, chewing gum basically "jams" the signal.
Listen to the whole song. If the Zeigarnik Effect is the culprit, the cure is completion. Go find the track on Spotify and listen to it from start to finish. Give your brain the closure it’s screaming for. Usually, once the "story" of the song is over, the brain is willing to let it go.
Engage in a "Goldilocks" task. You need a mental challenge that isn't too hard (which would cause stress) and isn't too easy (which allows the mind to wander). Anagrams or a moderately difficult Sudoku puzzle are perfect. You want to hijack the cognitive resources the earworm is currently using.
The "Cure" Song. Some people swear by having a specific "cure" song—a track they use to displace the earworm. For many, it’s "God Save the Queen" or "Happy Birthday." The idea is to replace the complex earworm with something so simple and short that it doesn't stick itself.
Is It Ever a Medical Issue?
For 99% of people, having a song runnin through my head is a harmless quirk of being human. It’s a sign your brain is active and healthy. However, in very rare cases, persistent musical loops can be a symptom of something else.

Palinacousis is a rare condition where a person continues to hear a sound after the stimulus has stopped. It’s often linked to issues in the temporal lobe. There is also "Musical Hallucinosis," which is more common in people with hearing loss. This isn't just a "stuck song"—it's the sensation of actually hearing music playing in the room when it isn't. If the music is accompanied by other symptoms like dizzy spells or severe headaches, that's when it's time to talk to a neurologist. But for most of us? It's just that annoying 80s synth-pop track again.
The Evolutionary Theory
Some evolutionary psychologists argue that earworms actually served a purpose before we had written language. In a world of oral traditions, the ability for a "chant" or a "verse" to keep runnin through my head was how we passed down vital information. Where to find water, which berries are poisonous, the history of the tribe—all of it was set to rhythm and rhyme.
The brain needed to be sticky.
We’ve evolved to be masters of audio retention. The fact that we now use that superpower to remember the lyrics to "Baby Shark" is just a modern irony. We are living with prehistoric hardware in a digital world saturated with 15-second TikTok sounds designed specifically to exploit these neural pathways.
Actionable Steps to Clear Your Mind
If the music won't stop, don't fight it with silence. Silence often makes it louder. Instead, try these specific tactics to regain control of your internal workspace:
- Verbalize something else. Read a book out loud or call a friend. Using your actual vocal cords is the most effective way to break an internal auditory loop.
- Change your environment. Walk into a different room or step outside. Sensory shifts can "reset" the brain's current background processes.
- Accept it. Sometimes the more you obsess over the song runnin through my head, the more power you give it. Acknowledge it ("Oh, I'm thinking of that song again") and try to refocus on a physical sensation, like the weight of your feet on the floor.
- The Power Nap. If you're truly stuck, a 20-minute nap can sometimes "clear the cache" of your short-term memory and stop the replay.
The reality is that music is one of the most powerful stimuli the human brain can process. It touches the limbic system, the auditory cortex, and the motor cortex all at once. Having a song runnin through my head isn't a sign of a broken brain; it’s a sign of a brain that loves patterns. Take a deep breath, grab a piece of gum, and let the rhythm fade out on its own terms.
