AtHeart Returns to 1996 With “3!4!”, the Second Single From TIME TRAVEL PROJECT

K-pop group AtHeart has released “3!4!”, the second single from their global remake series TIME TRAVEL PROJECT. The track is out now across all major streaming platforms.

“3!4!” first arrived in 1996 via Korean group Roo’Ra, and it quickly became one of the era’s defining hits. AtHeart filters the song through the group’s musical identity while keeping the bright energy and New Jack Swing foundation that made the original so memorable.

There is also a direct link between the two versions. Lee Hyun Do, one of the original songwriters, took part in the new arrangement.

Where the 1996 intro opened with ukulele, AtHeart instead reaches for warm electric piano and delicate guitar arpeggios, giving the song a softer, more melodic atmosphere without losing its upbeat spirit. All seven members, Michi, Arin, Katelyn, Bome, Seohyeon, Aurora and Nahyun, bring their own vocal colors to the track.

The result sits somewhere between 1996 and 2026, introducing a classic to a new generation while offering longtime listeners a fresh take on a familiar favorite.

The accompanying music video carries that same collision of eras into the visuals, with the members embracing styling drawn from the late 1990s and early 2000s. Previous releases leaned into the group’s more powerful side and their strength as performers. “3!4!” trades that for something brighter and more playful.

TIME TRAVEL PROJECT is AtHeart’s global remake series built around songs originally released in 1996. Across the project, the group takes on the role of musical “time travelers,” revisiting influential songs from three decades ago and presenting them to today’s listeners through AtHeart’s own sound and perspective.

The series launched earlier this summer with “Say It,” a reimagining of The Cardigans’ 1996 international hit “Lovefool.” With “3!4!,” AtHeart widens the concept by turning to one of Korea’s most recognizable songs from the same year.

“3!4!” is available now worldwide.
