You know that feeling when a song starts and you immediately want to walk down a city street like you own the place? That’s basically the entire vibe of Charlie Puth How Long. It’s got this bouncy, infectious bassline that makes you forget for a second that the lyrics are actually about a pretty mess confession of infidelity. Honestly, it’s a weirdly upbeat way to tell someone you’ve been "creepin' 'round."
Released back in late 2017 as the second single from his sophomore album Voicenotes, the track solidified Charlie’s shift from the "choir boy" pop of Nine Track Mind to a more sophisticated, R&B-influenced sound. It wasn't just a catchy tune; it was a statement. He wasn't just the "See You Again" guy anymore. He was making stuff that felt gritty, funky, and—most importantly—relatable in a "we've all made mistakes" kind of way.
The Story Behind the Bassline
Charlie Puth is a bit of a musical nerd, and I mean that in the best way possible. He famously has perfect pitch, which means he hears music in everything from a falling plate to a car horn. For Charlie Puth How Long, the production story is actually kind of wild.
Most people think these hits are made in multi-million dollar studios with dozens of engineers. Nope. Charlie actually produced and wrote most of the Voicenotes album—including "How Long"—on his tour bus. He used a tiny laptop and one broken speaker. Think about that for a second. One of the cleanest-sounding pop records of the decade was mixed in a cramped room while driving down a highway.

He’s called the song a "part two" to his previous hit, "Attention." While "Attention" was about a girl playing games with him, "How Long" flips the script. This time, he’s the one in the hot seat. The song is written as a dialogue. You have Charlie admitting, "I'll admit, I was wrong," while the "girl" in the song (voiced by Charlie's own falsetto in the chorus) is asking the titular question: How long has this been going on?
Why It Still Works in 2026
It’s been years since this track hit the Billboard Hot 100 (where it peaked at number 21, by the way), but it still feels fresh. Why? Because the production is timeless. It doesn't rely on the "trendy" synth sounds of 2017 that aged like milk. Instead, it leans into a 1980s-inspired funk groove that feels more like something Quincy Jones or Rod Temperton would have touched.
The lyrics are also brutally honest. Pop music is usually full of "you broke my heart" anthems. It’s much rarer to hear a massive radio hit where the singer says, "Yeah, I was drunk, I was gone, but there were no feelings involved." It’s an uncomfortable confession, but it feels human. It doesn't try to make him the hero.

The Mystery of the Inspiration
Fans have spent years trying to figure out who the song is about. Some people point to his rumored fling with Selena Gomez, especially since the music video features a brief shot of a painting that looks suspiciously like her. Charlie has always been a little coy about it. In interviews with Ryan Seacrest and Access Hollywood, he’s kept it vague, saying it’s a "personal experience" but leaving the specific names to the imagination.
Regardless of the muse, the song's brilliance lies in its structure. The way the bass drops out during the bridge—right before that whispered "how long has this been going on"—is a masterclass in tension. It mimics that stomach-dropping moment when you realize you've been caught.
Breaking Down the Production
If you’re a music gear head, you’ll appreciate this: Charlie used a "walking bassline" style for the track. His bass player, Dimitri, used a specific preamp that gave the notes a "bouncy" quality. Charlie described it as the sound of "walking down the street with a big cup of coffee."

The tempo sits right around 110 BPM. That’s the "sweet spot" for a groove—it’s not fast enough to be a dance track, but it’s too fast to be a ballad. It’s perfect for nodding your head in the car.
Actionable Takeaways for Music Fans
