Lee Ji-eun, who performs under the name IU, is a South Korean singer-songwriter and actress active since 2008.
This track was released in 2015 and reached No.
1 on the Korean charts.
It was used in the 2015 South Korean television drama The Producers.
Winter SleepIU27rank/position
The album “Pieces,” composed entirely of unreleased songs written and composed by IU herself.
Among them, “Winter Sleep” is a lullaby-like track with a gentle, unhurried melody.
Its lyrics, imbued with sincerity and intertwined with the passing of the seasons, slowly seep into the heart.
The song invites various interpretations—expressing feelings for a friend, of course, but it also seems to resonate deeply with the emotions one has for their own child.
The beauty of time spent with a loved one and the calm that envelops the heart are rendered with lyrical sensitivity through IU’s unique sensibility.
A room where one is aloneIU28rank/position
IU is a female artist loved by many for her cute looks and overwhelming vocal ability.
“The Room Where I’m Alone,” sung by IU, is a healing song I recommend listening to whenever you feel you need comfort.
Why not take this opportunity to give it a listen?
하루 끝 (Every End of the Day)IU29rank/position
A bright, uplifting number that feels so very IU.
It’s about not being able to express your feelings honestly, even though you’re truly in love, and wishing the person you like would confess their love to you.
The fact that IU sings a song like this—in the best way—makes it almost unbearable (lol).
It’s irresistibly cute and totally heart-fluttering! Even though the title is “End of the Day,” it makes you want to go out!
Twenty-three(스물셋)IU(아이유)30rank/position
A track from IU’s 4th mini album “CHAT-SHIRE,” created by IU herself—from writing and composing to producing—showcasing her exceptional vocal prowess.
The lyrics are fresh and mischievously cute, teasing with riddles while keeping you on your toes.
The music video is an adorable piece that starts with her plunging her face into a cake.
With purple—IU’s favorite color—as the theme, it portrays her artful world filled with animal motifs.
