IU

Lee Ji-eun (Korean: 이지은; born May 16, 1993), also known by her stage name IU (아이유), is a South Korean singer-songwriter and actress. She signed with LOEN Entertainment (now Kakao Entertainment) in 2007 as a trainee and debuted as a singer at the age of fifteen with the EP Lost and Found (2008). Although her follow-up albums brought mainstream success, it was only after the release of "Good Day", the lead single from her 2010 EP Real, that she achieved national stardom. "Good Day" went on to spend five consecutive weeks at the top of South Korea's Gaon Digital Chart, and in 2019, it was ranked number one on Billboard's "100 Greatest K-Pop Songs of the 2010s" list.

With the success of her 2011 albums, Real+ and Last Fantasy, IU established herself as a formidable force on the music charts of her native country and further cemented her girl next door image as Korea's "little sister". Her musical style matured and evolved with subsequent releases, deviating from mainstream K-pop styles, exploring and mixing various music genres, with IU exerting more creative control over her music, both as lyricist and producer, at the same time consistently retaining her dominance on South Korean music charts. Her 2020 single "Eight" (prod. by Suga) became her first to reach number one on Billboard's World Digital Song Sales chart.
