He was literally dancing on walls. In 2017, Charlie Puth dropped a music video that felt like a fever dream, featuring him defying gravity against the backdrop of a Los Angeles cityscape. But beneath the slick "pop-funk" production and those infectious bass lines, the track How Long carried a weight that most fans totally missed at first. It wasn't just a catchy radio hit; it was a gritty, uncomfortable confession about infidelity.
It’s funny how time works. We’re sitting here in 2026, and Charlie is a married man now, expecting his first child with Brooke Sansone. He’s about to kick off the Whatever’s Clever! World Tour. But back when he wrote this, he was a 25-year-old trying to prove he wasn't just the "See You Again" guy. He was messy. He was making mistakes. And honestly, he was incredibly honest about it.
The Story You Weren't Supposed to Hear
Most pop stars try to look like the hero. Not here. In "How Long," Charlie plays the villain. He’s the one who cheated. He’s the one getting caught. The lyrics are basically a transcript of a fight.
"I'll admit, I was wrong, what else can I say, girl?"
That’s a bold way to start a chorus. He’s not making excuses—well, actually, he is. He tries that classic, "Can't you blame my head and not my heart?" line. It’s a terrible excuse, right? But it’s a very human one. We’ve all seen people try to logic their way out of a feelings-based disaster.
The song actually functions as a sequel. If you listen to "Attention," it’s about a girl messing with his head. Then comes "How Long," where he admits he was the one who stepped out. He’s called it "Part Two" of the story. It’s like a cinematic universe of bad relationship decisions.

Why It Sounds So Different
You might notice the bass. It’s thick. It’s driving. Charlie produced this himself—mostly on a tour bus with one broken speaker. Think about that for a second. One of the biggest hits of the decade was mixed in a cramped, vibrating metal tube on a highway.
He wanted that "dark R&B" vibe. He was obsessed with the late '80s sounds of Jimmy Jam and Terry Lewis. He didn't want a "ripoff" of "Attention," so he moved the key to C-minor. It gives the song this moody, urban grit that his earlier stuff totally lacked.
The Mystery Woman
Who is it about? Fans have been obsessed with this for years. For a long time, everyone pointed fingers at Selena Gomez. They had that "We Don't Talk Anymore" era, and the timeline sorta fit. Charlie has always been a bit of a tease about it. He told Billboard back in the day that the relationship was "very short-lived, very small, but very impactful."
But honestly? It doesn't really matter if it’s about a celebrity. The power of the song comes from the universal panic of being asked, "How long has this been going on?"
That moment where the floor drops out.

Chart Stats That Matter
The song wasn't just a viral moment; it had serious legs.
- It peaked at Number 21 on the Billboard Hot 100.
- In the UK, it hit Number 9.
- It stayed on the charts for months, eventually going 3x Platinum in the US.
That’s 3 million units moved. People weren't just listening; they were relating. Or maybe they just liked the way he hit those falsetto notes in the bridge. Either way, it cemented him as a producer-first artist.
Defying Gravity in the Music Video
The video is iconic for the suit alone. Charlie is dancing through the streets, literally walking up the sides of buildings. It was directed by Emil Nava. The "gravity-defying" look wasn't just a gimmick; it represented the feeling of being "on top of the world" while simultaneously having your life fall apart.

It’s the ego. When you’re cheating and getting away with it, you feel invincible. You’re walking on walls. Then the song ends, the music stops, and you’re just a guy standing in the middle of a street, alone.
2026 Perspective: How It Aged
Looking back now, "How Long" was the bridge to the Charlie Puth we have today. Before Voicenotes, he was a bit too "polite." This song gave him edge. It showed he could be a "jerk" in his music and still be likable because he was being real.
Nowadays, he’s much more settled. His new album Whatever's Clever! is supposedly much more grounded, reflecting his life with Brooke. But you can still hear the DNA of "How Long" in his production—that clean, snappy percussion and the way he layers his own vocals to sound like a choir of one.
If you’re heading to his 2026 tour, expect this to be a highlight. He usually does a "breakdown" version where he shows the audience how he built the beat on his laptop. It’s a masterclass in pop construction.
Next Steps for the Fan
If you want to dive deeper into the technical side of the track, check out Charlie’s old "Behind the Notes" videos on YouTube. He shows the exact "voicenotes" that started the melody. Also, if you’re planning on catching the 2026 tour, tickets go on general sale January 16. Make sure your Ticketmaster account is updated; those stadium dates in LA and London are going to vanish fast.
Lastly, give the Voicenotes album a full spin from start to finish. It’s a perfect time capsule of 2017/2018 pop-funk that still sounds remarkably fresh today.
