You know the feeling. You’re sitting in traffic, or maybe just staring at a wall, and suddenly a high-pitched, Caribbean-infused voice starts echoing in your skull. It’s persistent. It’s relentless.
"Shawty's like a melody in my head..."
Most people call the song "Shawty Like a Melody," but its real title is actually "Replay." Released in the summer of 2009 by Iyaz, a singer from the British Virgin Islands, it did exactly what the lyrics promised. It got stuck. It stayed there. And somehow, nearly two decades later, it’s still living rent-free in the collective consciousness of the internet.
It’s honestly kind of weird. How does a song about an iPod—a device that is basically a museum relic now—manage to stay so relevant?
The Mystery of the "Sean Kingston" Song
If you ask a casual listener who sang "Replay," there’s a massive chance they’ll say Sean Kingston.
They’re wrong, but they’re also kind of right.
Sean Kingston didn't sing it, but he was the guy who discovered Iyaz on MySpace. Back then, MySpace was the Wild West of the music industry. Kingston liked what he heard, reached out, and eventually, Iyaz was signed to Beluga Heights Records, the label run by producer J.R. Rotem.

Because the "island-pop" sound was so closely associated with Kingston (think "Beautiful Girls"), the two artists often get blurred together in people's memories. In fact, "Replay" was originally intended for Sean Kingston’s own album, Tomorrow. He passed on it. Imagine being the guy who turned down a triple-platinum hit that would eventually become a permanent part of meme history.
J.R. Rotem’s production is the secret sauce here. You can hear his signature at the very start of the track—that "J-J-J-J-J.R." tag. It’s the same polish he gave to Jason Derulo’s "Whatcha Say."
Why We Can't Stop Singing "Na-Na-Na-Na"
The lyrics aren't exactly Shakespeare. Let's be real.
Iyaz sings about meeting a girl at the mall with her friend. He was scared to approach her. He talks about cooking things she likes in the kitchen. It’s wholesome, almost innocent compared to the R&B that dominates the charts today.
But the hook? That’s where the magic happens.
- The Simile: Comparing a girl to a melody is a classic trope, but it’s the execution that sticks.
- The Tech: Referencing an iPod "stuck on replay" was peak 2009. It’s nostalgic now, like hearing a song about a Walkman or a discman.
- The Phonetics: "Na-na-na-na" is a universal language. You don't need to know English to hum along to the bridge.
The song peaked at number two on the Billboard Hot 100, held back from the top spot only by Kesha’s "Tik Tok." It was a global juggernaut, hitting number one in the UK, Australia, and Switzerland.

The TikTok Resurrection and "Rickrolling"
Around 2020, the song underwent a strange transformation. It wasn't just a nostalgic hit anymore; it became a weapon.
Gen Z started using "Replay" as a new version of the Rickroll. You’d be watching a video—maybe a tutorial or a dramatic clip—and right at the climax, the audio would cut to Iyaz’s "Shawty's like a melody."
It was jarring. It was funny. It was everywhere.
One of the most famous iterations involved a guy singing the lyrics in a booming, operatic voice on a city street. Another involved a screenshot of a text conversation where a user had a signature turned on that added the lyrics to every single message they sent. "Hey are you coming to dinner? Shawty's like a melody in my head."
This memeification gave the song a second life. On YouTube, the official music video and its "prequel" have racked up over 400 million views. People aren't just listening for the music; they’re participating in a digital inside joke that spans generations.
The Tragic Irony of Sean Kingston
While the song Iyaz made famous stays lighthearted and fun, the man who helped bring it to life has had a much darker path lately.

In a twist that sounds like a movie script, Sean Kingston and his mother were indicted on federal wire fraud charges in 2024. By March 2025, they were convicted. It’s a sharp contrast to the sunny, "island-pop" vibes of the late 2000s. Kingston, who once toured with Beyoncé and Justin Bieber, found himself at the center of a $1 million fraud scheme involving luxury goods and fake payments.
It makes the nostalgia of "Replay" feel a bit bittersweet. That era of music felt so untouchable and bright, but the reality for the creators hasn't always matched the "melody in our heads."
How to Handle an Earworm
If you’ve read this far, the song is probably playing in your head right now. Sorry about that.
Psychologists call these "involuntary musical imagery." The best way to get rid of an earworm isn't to fight it, but to listen to the song in its entirety. Your brain often loops the hook because it feels "unfinished." By listening to the whole three minutes and four seconds of "Replay," you give your brain a sense of closure.
Actionable Insight: Next time you find yourself humming "Na-na-na-na," take a moment to look up the 2009 music video. Notice the fashion—the oversized vests, the baggy jeans, the early-model iPhones. Embrace the nostalgia. It’s a reminder that even in a world of fast-moving trends, a simple, catchy melody can outlast the technology it was written about.
