Kill This Love was released by BLACKPINK in April 2019 as the title track of their EP of the same name, and its dramatic brass-led opening quickly became one of the group's most recognisable sounds. Short clips of that opening have circulated widely in fan edits, reaction videos, and short-form posts, where the alert-style cut works as a shorthand for confidence and drama. Its popularity endures because the hook is instantly recognisable even without lyrics, making it easy to reuse across new trends.
