Zimzalabim

"Zimzalabim" is a song recorded by South Korean girl group Red Velvet for their sixth Korean extended play The ReVe Festival: Day 1, which acts as the first installment of the group's The ReVe Festival trilogy. Primarily an EDM-influenced electropop track that resembles a "colorful parade" and showcases an extravagant soundscape, the song was composed by production duo Caesar & Loui, Ollipop and Hayley Aitken with Korean lyrics written by lyricist Lee Seu-ran, which tells the listeners to "unfold a dream" that is "held deeply" in their heart. Accompanied by an amusement park-themed music video, it was released on June 19, 2019 by SM Entertainment as the lead single for Day 1, and subsequently the first single from The ReVe Festival trilogy.

Upon its release, "Zimzalabim" polarized music critics over its "genre-hopping" composition. While some felt the song was a "downhill" from the group's previous experimenting tunes, others saw the song as a sonic roller coaster ride and praised its "energetic, anthemic" sound. It also attained moderate success, becoming their first lead single to miss the top ten on Gaon Digital Chart, peaking at number eleven, while earning Red Velvet their fourteenth consecutive top-ten entry on Billboard's World Digital Songs chart. The song also marked the group's first chart appearance in Oceania, peaking at number thirty-nine on New Zealand Hot Singles Chart.
