AMPERS&ONE Albums & Singles

Debut Song: “On And On”

The moment AMPERS&ONE dropped their debut track “On And On”, K-Pop got a little louder, a little cooler, and a whole lot catchier.

“On And On” kicks off with an upbeat rhythm and a chorus that sticks like glitter on concert merch. It’s a feel-good anthem with major replay value, serving classic K-Pop vibes with a modern twist. 

From the vocals to the choreography, it’s clear these boys didn’t come to play. They came to slay.

“Broken Heart” – Love at First Beat

In March 2024, AMPERS&ONE unveiled their second single album, One Hearted, featuring the title track “Broken Heart.” This hip-hop dance number pulses with a heavy bass line, capturing the exhilarating sensation of falling in love at first sight. The track’s dynamic rhythms and emotive lyrics showcase the group’s ability to blend energetic beats with heartfelt storytelling. The accompanying music video complements the song’s intensity, offering a visual feast that mirrors the song’s passionate undertones. ​

“He + She = We” – The Equation of Love

October 2024 saw the release of AMPERS&ONE’s first extended play, One Question, with “He + She = We” as its lead single. This funky house track combines catchy rhythms with an energetic melody, exploring the complexities of love through a playful lens. The song’s lyrics explore the idea that love isn’t just about two individuals but about the unity they create together. The music video amplifies this theme, presenting a vibrant and sporty aesthetic that encapsulates the group’s youthful charm. ​

“Kick Start” – Revving Up the Energy

April 2025 marked a bold new direction for AMPERS&ONE with the release of their second extended play, Wild & Free.

The music video, set in a whimsical bungeoppang factory, uses imaginative visuals to convey the idea that our fears are often larger in our minds than in reality.
