KiiiKiii's 'WhyKiiiKiii' sweeps charts: all 6 tracks chart, first-week sales double previous album

KiiiKiii (지유, 이솔, 수이, 하음, 키야) dropped mini album 3 WhyKiiiKiii on August 10. It's their first release in roughly seven months since Delulu Pack in January.

All six tracks charted on Apple Music's Top 100: South Korea, Melon HOT100, and Spotify Korea Top 200. Title track Pop Off Pop Off claimed #1 on Bugs real-time, Apple Music Top 100: South Korea, Apple Music Top 25: Seoul, and Melon HOT100 on release day, then peaked at #24 on Melon TOP100. By August 17 at 8 AM, it held #1 on Bugs real-time and #3 on Spotify Korea. The MV went straight to #1 on YouTube Music Video Trending Worldwide and topped YouTube Music's Popular Rising Music chart.

WhyKiiiKiii hit #1 on iTunes Top K-pop Music Albums in France, the Netherlands, and Australia. It landed top 10 in 13 countries including the US, UK, Canada, and Japan. The album also placed top 3 across all major Chinese city charts on Apple Music.

First-week sales came to approximately 82,000 copies. That's double the ~41,000 Delulu Pack sold in January.

Context matters here. Previous title track 404 (New Era) topped Melon TOP100 and the Circle Chart monthly chart. It charted on Billboard Global (excl. US) for eight consecutive weeks and landed at #1 in Billboard's "Best 25 K-pop Songs of 2026 (So Far)" list from July.
