It started with a single tweet and ended up becoming one of the messiest, most successful collaborations in the history of modern dance music. When Calvin Harris dropped "This Is What You Came For" in 2016 featuring Rihanna, everyone knew it was a hit. It had that specific, polished EDM-pop veneer that Harris had spent years perfecting. But under the surface of those "you-oo-ous," there was a brewing storm involving Taylor Swift, a pseudonym, and a breakup that played out on the global stage.
Honestly, it’s rare for a song to be both a technical masterpiece of production and a primary document in a celebrity feud.
Most people just remember the lightning bolt on the single cover. Or maybe they remember Rihanna’s effortless vocals. But the real story of this is what you came for song is about the shift in how pop music is manufactured and credited. It represents the peak of the tropical house influence that dominated the mid-2010s, yet it somehow feels more durable than the tracks that tried to copy it.
The Nils Sjöberg Mystery and the Secret Songwriter
For a few months, if you looked at the liner notes for the track, you’d see the name Nils Sjöberg. Nobody knew who that was. It sounded Swedish, which made sense because Sweden basically runs the pop industry, but the mystery didn't last.
The truth came out in the most dramatic way possible: through a rep for Taylor Swift.
Swift had written the song on a piano and sent a demo to Harris. They recorded a full demo with her vocals, but they ultimately decided that having two of the biggest stars in the world on one track would overshadow the music itself. So, they brought in Rihanna. Taylor stayed on as a backing vocalist—you can actually hear her high-pitched harmonies during the "ooh" sections if you listen closely enough—and took the pen name Nils Sjöberg to keep the focus on the collaboration.
Then the breakup happened.

The relationship between Harris and Swift soured, and suddenly, the "secret" wasn't a secret anymore. Harris took to Twitter in a now-deleted rant, confirming Taylor wrote the lyrics and melody but emphasizing that he "wrote the music, produced the song, arranged it and cut the vocals." It was a rare, raw look at the friction that happens when two creative powerhouses collide.
Why the Production Actually Works
Strip away the drama and you’re left with a very lean, very efficient piece of music. Calvin Harris is a master of "less is more."
The song doesn't rely on a massive, aggressive drop like the dubstep-influenced EDM of 2012. Instead, it uses a soft, pulsating synth bass and a simple four-on-the-floor beat. The "lightning" everyone talks about is the vocal chop. That repetitive, rhythmic "you" serves as the hook, the bridge, and the emotional anchor.
It’s genius, really.
By chopping Rihanna’s voice into a percussive element, Harris turned the vocal into an instrument. This wasn't a new trick, but he did it with a precision that made it inescapable on the radio. The song peaked at number three on the Billboard Hot 100, but its cultural footprint felt like a number one. It was everywhere—gyms, malls, festivals, car radios.
The track also benefited from the "Rihanna effect." She has this specific ability to sound bored and incredibly emotive at the same time. On this is what you came for song, she delivers the lines about lightning striking every time she moves with a cool detachment that makes the song feel expensive.

The Impact on the EDM-Pop Crossover
We have to talk about where music was in 2016.
The world was transitioning. We were moving away from the "raucous party" vibe of early David Guetta and into something more "chill." This track was the bridge. It was danceable, but it wasn't exhausting. It paved the way for the "AirPods pop" era—music that sounds just as good in headphones while you're walking to work as it does in a club in Ibiza.
Several artists tried to recreate this specific formula:
- Minimalist verses that build tension.
- A "hollow" chorus that relies on a synth lead rather than a big vocal belt.
- Heavy use of side-chain compression to make the track "breathe" with the kick drum.
But most of them failed because they lacked the specific chemistry of the Harris-Rihanna-Swift triangle. You had the world’s biggest DJ, the world’s coolest pop star, and the world’s most successful songwriter all touching one four-minute track. That’s a statistical anomaly.
A Legacy of Credits and Ownership
The fallout from this song actually changed how people look at song credits. It made fans realize that the "Produced by" tag often hides a lot of the heavy lifting. Swift eventually reclaimed her credit, and Nils Sjöberg was retired. If you look at the BMI or ASCAP databases now, her real name is right there.
It also served as a turning point for Calvin Harris. After this, he pivoted hard toward Funk Wav Bounces Vol. 1, moving away from the sleek EDM sound into 70s-inspired funk and disco. It was almost as if "This Is What You Came For" was his final statement on the genre—the most perfect version of that sound he could possibly make before moving on.

The music video, featuring Rihanna in a giant cube with projections, has racked up billions of views. It’s a time capsule of a specific aesthetic: neon, minimalism, and high-fashion streetwear. It’s also notable for what it doesn't have. Calvin Harris barely appears in it. It’s all Rihanna.
Actionable Takeaways for Music Fans and Creators
If you're a songwriter or just someone who loves the technical side of music, there are a few things to learn from the success of this is what you came for song.
Simplicity is a Choice
Don't overcomplicate your "hook." The most memorable part of this song is a single syllable repeated over a syncopated beat. If your melody is strong enough, you don't need fifty layers of sound to hide behind.
Pseudonyms and Branding
The Nils Sjöberg incident shows that branding is often more important to labels than the art itself. If you're collaborating, establish credit early. Digital footprints last forever, and the "surprise" reveal of a songwriter can sometimes overshadow the work itself.
Study the Vocal Chop
If you're a producer, analyze how Harris tuned the vocal chops in this track. They aren't just random sounds; they follow the chord progression strictly and act as a secondary lead melody. This is why the song feels so "full" despite having relatively few instruments playing at once.
Listen for the "Ghost" Harmonies
Go back and listen to the song with high-quality studio headphones. Focus on the high-end frequencies during the chorus. You can hear Taylor Swift’s "oohs" layered under Rihanna’s lead. It’s a masterclass in how to use a background vocal to add texture without changing the character of the lead singer's voice.
The song remains a staple of DJ sets for a reason. It bridges the gap between pop fans and dance music purists. While the drama of 2016 has faded into the background of celebrity history, the track itself remains a blueprint for how to write a global smash that doesn't sacrifice its soul for the charts.
