APT. (song)

"APT." is a song by New Zealand and South Korean singer Rosé and American singer-songwriter Bruno Mars. It was released through The Black Label and Atlantic Records on 18 October 2024, as the lead single from Rosé's debut studio album, Rosie (2024). "APT." marked Rosé's first solo single in three years and her first release since departing from YG Entertainment and Interscope Records in 2023. The song was written and composed by various contributors, including Rosé and Mars, and includes elements from the 1982 tune "Mickey" by Toni Basil. It is an up-tempo pop, pop rock, pop-punk, and new wave track, featuring indie rock and electropop influences. Inspired by a South Korean drinking game, the song's chorus is built around the game's rhythmic chant of apateu (Korean: 아파트; lit. 'apartment'; pronounced [a̠pʰa̠tʰɯ]). Critics lauded "APT." for its catchy production, broad cross-cultural appeal, and its role in promoting Korean culture worldwide. It was the best-selling global single of 2025 according to the International Federation of the Phonographic Industry (IFPI), marking the first time an artist outside of North America or Europe topped the IFPI Global Single Chart and the first song with non-English lyrics to do so. The song spent 12 weeks atop the Billboard Global 200, becoming Rosé and Mars's second number-one single each and the number-one song on the 2025 year-end chart. In South Korea, it peaked at number one on the Circle Digital Chart for ten weeks. "APT." was the first song by a K-pop female soloist to top Australia's ARIA Singles Chart and the first Western song to top the Billboard Japan Hot 100 in over a decade. The song saw huge global success, topping the charts in over 50 countries including Austria, Belgium, Canada, Germany, Indonesia, New Zealand, Norway, the Philippines, Sweden, Switzerland, and Taiwan.
