It starts with a single bassline. Maybe a high-pitched synth hook you heard for three seconds in a CVS aisle while looking for toothpaste. Suddenly, your brain is a broken record. You’re trying to sleep, or draft a budget, or have a serious conversation about your mortgage, but your internal monologue is just the chorus of a 2011 Katy Perry song on a relentless, high-definition loop. It’s maddening.
We call them earworms. Researchers like Dr. Vicky Williamson, an expert on the psychology of music, prefer the term "Involuntary Musical Imagery" (INMI). Honestly, most of us just call it a mental itch that we can't scratch. Understanding how to get a song out of your head isn't just about willpower; it’s about tricking a specific part of your cognitive hardware into resetting itself.
Your brain isn't trying to annoy you. Usually, it's just trying to finish a pattern.
The Zeigarnik Effect and Your Looped Brain
Ever noticed that you rarely get the whole song stuck? It’s almost always a fragment. A bridge. A specific four-bar phrase. This happens because of a psychological phenomenon known as the Zeigarnik Effect. Back in the 1920s, a Soviet psychologist named Bluma Zeigarnik noticed that waiters could remember complex orders perfectly until the food was delivered, at which point the memory vanished.
Your brain hates unfinished business.
When you only know part of a song, your mind keeps looping that segment in an attempt to "resolve" the tension and reach the end. It’s an open loop. Since you don’t know the next lyric or the way the melody resolves into the outro, the "file" stays open in your working memory.

The simplest, most counterintuitive way to stop this is to actually listen to the full song. Start to finish. No skipping. By hearing the final notes, you give your brain the "completion" signal it’s been hunting for. The file closes. The loop breaks.
Why Chewing Gum Actually Works
If listening to the song feels like pouring gasoline on a fire, reach for a pack of Orbit. Seriously.
A study from the University of Reading found that chewing gum significantly reduces the recurrence of earworms. It sounds like a "one weird trick" headline, but the science is solid. The act of chewing uses the same sub-vocal motor pathways we use to "sing" along in our heads.
Basically, your brain has a limited amount of bandwidth for "inner speech." When you chew vigorously, you’re essentially jamming the signal. You’re giving the motor cortex a task that competes with the mental rehearsal of the music. It’s hard for the brain to keep the rhythm of "Espresso" going when your jaw is busy grinding through a piece of peppermint gum.
The Goldilocks Zone of Distraction
You can't just think about "nothing." That’s how you end up humming the song again within thirty seconds. You need a task that hits the "Goldilocks Zone"—not too easy, not too hard.

If you try to do something mindless, like washing dishes, the song will fill the empty space. If you try to do something incredibly stressful, like your taxes, the song might act as a coping mechanism for the stress. You need a moderate cognitive load.
Try these instead:
- Anagrams: Try to find five words within a longer word like "Atmosphere" or "Chandelier."
- Sudoku: Not the "expert" level ones that make you want to cry, but a medium-difficulty puzzle that requires active sequencing.
- Reading: Not a light Instagram caption, but a page of a dense novel or a technical article.
Research published in Applied Cognitive Psychology suggests that these verbal and mathematical tasks compete for the same resources as the earworm. When you engage your "phonological loop"—the part of your working memory that deals with auditory information—you're effectively evicting the song to make room for the words or numbers you're processing.
The Weird Connection to Stress and Fatigue
Earworms aren't just about the music. They're about your state of mind.
Dr. Williamson's research has shown that we are much more susceptible to involuntary musical imagery when we are tired or stressed. When our executive control is low, the brain's "filter" weakens. This allows repetitive thoughts to bubble up more easily. If you find yourself stuck with a particularly sticky melody during a late-night study session or a long drive, it might be a signal that your brain is simply overtaxed.
There's also the "rebound effect." If you try too hard to suppress the song—clapping your hands over your ears and shouting "stop it!"—you're likely to make it worse. This is the "White Bear" problem in psychology: if I tell you not to think of a white bear, it's the only thing you'll see.

When a Song Becomes a Symptom
For 99% of people, an earworm is a minor annoyance. For a very small percentage, it can be more intense.
In rare cases, persistent musical loops can be linked to Obsessive-Compulsive Disorder (OCD) or even specific types of musical hallucinosis. However, these are usually accompanied by other symptoms, like high anxiety or the actual perception of sound coming from outside the head. If the song is just "playing" in your mind’s ear, you’re in the normal camp.
Interestingly, some people find that their earworms have a "functional" purpose. Your brain might pull up a fast-paced song when you're feeling sluggish to try and wake you up. Or it might play a nostalgic track during a period of loneliness. The brain is an incredible, albeit sometimes annoying, self-regulator.
Actionable Steps to Kill the Loop
Stop fighting the song and start managing your cognitive load. Here is the exact sequence to follow next time you're stuck in a musical rut:
- The Completion Strategy: Find the song on YouTube or Spotify. Listen to it from the very first second to the very last. Focus specifically on the ending. Visualize the "The End" screen in your mind.
- The Jaw Hack: Grab a piece of gum or even a toothpick. Engage your jaw muscles. This disrupts the sub-vocalizing process that keeps the song alive.
- The Verbal Pivot: Start a conversation or read out loud. Engaging your vocal cords and your verbal processing center is the most effective way to "overwrite" the musical data.
- The "Cure" Song: Many people have a specific "cure song" that doesn't get stuck but "cleanses" the palate. For many, it’s "Happy Birthday" or the National Anthem. These are songs so familiar and structurally simple that they act like a mental reset button without becoming new earworms themselves.
- Let it Fade: If all else fails, acknowledge the song. Say, "Okay, I'm thinking about this song right now." Acceptance reduces the stress of the "White Bear" effect, allowing the neural firing to naturally diminish over time.
The goal isn't to force the silence. It's to give your brain something better—or at least something more active—to do. Once you break the "open loop" of the melody, the silence usually follows on its own.
Next Steps for Long-Term Relief
To prevent frequent earworms, pay attention to your "trigger" environments. If certain stores or playlists always leave you with a mental loop, try wearing headphones with spoken-word content like podcasts. Research indicates that speech is much less likely to trigger the Zeigarnik effect than repetitive melodic structures. Additionally, managing sleep hygiene can strengthen your executive control, making your brain more "sticky-resistant" to unwanted background loops.
