KiiiKiii's '404 (New Era)' tops Billboard's 2026 Best K-pop Songs staff pick list

The track is the title song from the group's second mini-album Delulu Pack, released in January. UK house and garage production frames lyrics that take the internet error message "404 Not Found" and reframe it as freedom from any fixed standard or coordinate. Billboard wrote that KiiiKiii "completely twisted the most common error code on the internet with their own perspective and gave it new meaning." The outlet also noted the track "does not simply sing about a new era, but uses various elements in the lyrics to lead the audience into that worldview," adding that "the confidence and bold stage performance shown as a rookie group supports this."

Domestically, 404 (New Era) hit No. 1 on Melon's Top 100 and topped Circle Chart's monthly digital and streaming charts. Internationally, it charted on Billboard's Global (excl. U.S.) for eight consecutive weeks and marked KiiiKiii's first-ever entry on the Global 200. Delulu Pack itself entered the iTunes K-pop Top Albums chart in 19 countries and regions.

KiiiKiii — Jiyu, Isol, Sui, Haeeum, and Kiya — officially debuted in March of last year. Their debut track I DO ME earned them a win on MBC's Show! Music Core just 13 days after release. They closed out their debut year with 13 trophies at year-end ceremonies, including Music Video of the Year. (Thirteen trophies in year one from a group that didn't exist two years ago.)

The group is scheduled to return with a new album in mid-August. Season 2 of their variety series KiKiPangPang drops every Wednesday at 7 PM on their official channel.
