Here BLACKPINK rose to fame thanks to their smash hit "As If It's Your Last", which moved over 2 million units and boosted other singles like "DDU-DU DDU-DU" (their biggest hit to date, with almost 2.5 million units) and "BOOMBAYAH" (1.3M SPS).
These singles helped build hype for their newest era, and "KILL THIS LOVE" became a hit upon release. The song has spent 3 of its 4 weeks on chart at number #1, and it has only slipped to #2 on its fourth week. It's their best selling single in the pure format, and should be getting a 2x Platinum certification next week.
Numbers aside, BLACKPINK have truly influenced the introduction of K-Pop into the country's music scene, with acts like BTS, Seventeen or LOOΠΔ slowly making their way through the charts.
