It’s usually the worst possible song. You’re sitting in a high-stakes board meeting or trying to fall asleep at 2:00 AM, and suddenly, a three-second loop of a laundry detergent jingle starts playing on a loop in your skull. It won't go away. You try to think about something else, but the melody just gets louder. Having a song stuck in my head—or yours—isn't just a minor annoyance; for some, it’s a genuine cognitive disruption that lasts for days.
Scientists call these "earworms." The technical term is Involuntary Musical Imagery (INMI). Research suggests that roughly 98% of us experience this phenomenon. It’s a quirk of how our brains process auditory information and memory. We aren't just "remembering" a song; our brain is essentially "itching" an acoustic itch.
The Science of the Persistent Earworm
Why does this happen? James Kellaris, a researcher at the University of Cincinnati, often describes it as a brain itch that can only be scratched by repeating the melody. When we listen to music, it triggers the auditory cortex. For most of us, when the music stops, the brain keeps "playing" it to fill in the gaps.
It’s about repetition and simplicity. Most earworms share specific characteristics: they are fast-paced, have a generic melodic contour, and contain some unusual intervals or repetitions that catch the brain off guard. Think of the "Baby Shark" phenomenon or the chorus of a Lady Gaga track. Dr. Kelly Jakubowski at Durham University conducted a massive study and found that songs with "easy-to-remember" structures but "unusual" rhythmic patterns are the most likely candidates to get stuck in my head for hours on end.

The brain's motor cortex is also involved. Even if you aren't singing out loud, your brain is often simulating the movements required to sing or hum the tune. This creates a feedback loop. Your brain "hears" the song, prepares the "voice" to sing it, and then hears it again internally.
Why Stress Makes It Worse
If you’ve ever noticed that songs get stuck more often when you're overwhelmed, you aren't imagining things. Stress and anxiety act as catalysts. When the mind is wandering or fatigued, its inhibitory control—the ability to filter out intrusive thoughts—weakens.
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 know the chorus of a song, your brain views it as an "unfinished task." It keeps playing the loop over and over, trying to find the resolution or the end of the song that it can't quite reach.

It's honestly a bit cruel. Your brain is trying to be helpful by "finishing" the pattern, but because you don't know the rest of the lyrics, it just restarts at the beginning of the loop.
Common Triggers You Might Not Notice
- Recent Exposure: This is the obvious one. You heard it on the radio.
- Word Association: Someone says "umbrella," and suddenly Rihanna is performing a private concert in your frontal lobe.
- Emotional State: Certain tempos match our current heart rate or mood.
- Boredom: An under-stimulated brain will often generate its own entertainment.
How to Get the Song Out of Your Head
Most people try to fight it. They try to "not think about it." That’s a mistake. If I tell you "don't think about a pink elephant," what’s the first thing you see? Exactly. The same applies to music.
One of the most effective methods—and this sounds counterintuitive—is to listen to the song in its entirety. By listening to the whole track from start to finish, you provide the brain with the "resolution" it’s looking for. You close the loop. This effectively "solves" the Zeigarnik Effect.

Another weird but scientifically backed trick? Chew gum. A study published in the Quarterly Journal of Experimental Psychology found that the act of chewing gum interferes with the "subvocal rehearsal" (that internal humming) needed to keep an earworm alive. If your jaw is busy chewing, your brain struggles to simulate the singing.
When the Music Won't Stop: The Limits of Normalcy
For the vast majority of people, an earworm is a harmless quirk. However, in rare cases, it can cross the line into something more serious. There is a condition known as "Musical Hallucinosis," where people hear music so vividly they believe it is playing in the room. This is often linked to hearing loss or specific neurological conditions.
If a song is stuck in my head to the point where I can't function or it causes genuine distress, it might be a symptom of Obsessive-Compulsive Disorder (OCD) or high-level anxiety. In these instances, the "stuck" song isn't just an earworm; it’s an intrusive thought. If you find yourself in this category, standard "gum-chewing" tricks probably won't cut it.
Actionable Strategies to Reclaim Your Silence
- Engage in a High-Load Cognitive Task: Try a crossword puzzle or a complex math problem. You need something that uses the same "verbal" resources as the song. Watching TV usually isn't enough because it's passive.
- The "Cure" Song: Many people have a specific song they use to "overwrite" the earworm. For some, it’s "Happy Birthday" or the National Anthem. Be careful, though—you might just end up with the cure song stuck instead.
- Engage the Vocal Cords: Hum a different tune. This forces the motor cortex to switch gears.
- Acceptance: Sometimes, acknowledging the song and just letting it play in the background without fighting it causes the brain to lose interest. The more you "try" to stop it, the more importance the brain assigns to the thought.
The next time a 90s pop hit decides to move into your brain uninvited, don't panic. It's just your auditory cortex doing a bit of unprompted housekeeping. Put on the full track, grab a piece of gum, and let the loop finish. Your brain will eventually find something else to obsess over—hopefully something a little quieter.
To move forward, identify if your current earworm is triggered by a specific "unfinished" lyric. If so, look up the full lyrics and read them while listening to the track. This deliberate completion often signals to the brain that the "task" is over, allowing the mental loop to finally break. Alternatively, engage in a task that requires heavy use of your "inner voice," like writing a detailed email or reading a difficult book aloud, to crowd out the musical imagery.
