IU Popular Song Ranking [2026] (31–40)
The red shoesIU36rank/position
The nation’s little sister, IU, isn’t just about being cute! In this song, you get a jazzy, mature IU, and in the uptempo parts, a bright and cute IU.
She sings about a summer romance that has passed—perhaps it’s layered over the “red shoes” that take her into a fun dance time? And like waking from a dream, the joyful moments come to an end—there’s a touch of bittersweetness in this song.
A Beautiful Person (Feat. Balming Tiger)IU37rank/position
A collaboration between IU and Balming Tiger included on the remake album Flower Bookmark 3, which modernly reinterprets classic Korean songs.
Based on a 1974 track by Shin Joong-hyun, it features a striking arrangement that fuses IU’s gentle vocals with experimental sounds.
Released in May 2025, it also drew attention for its music video starring Cha Eun-woo.
The fantastical story—where a man and a woman born as beings of light meet while wearing masks—is memorable, and the song showcases IU’s new musical challenges.
It’s also recommended for anyone who wants to experience a masterpiece from the history of Korean music!
DramaIU38rank/position
It’s one of IU’s signature concert songs.
The recorder’s timbre and other elements are striking, giving it a fairytale-like soundtrack vibe—such a cute track.
It feels like she overlays the happy moments with her lover onto a drama.
When the romance ends, she’s left alone on the set, and before she knows it, the love story has already been wrapped up.
That’s so heartbreaking, isn’t it?
Graduation Day (졸업하는 날 / The Day of Graduation)IU39rank/position
Some of you may be about to part ways with friends because of graduation, or may have already done so.
In that case, I’d like to introduce “Graduation Day (졸업하는 날 / 卒業する日).” It’s a song released in 2009 by the singer-songwriter IU.
The lyrics express the sadness of saying goodbye to friends at graduation, the hope of meeting again, and the belief that many good fortunes will come your way in the meantime.
With such an uplifting message, it’s the kind of song that might blow away those feelings of loneliness when you listen to it.
Merry Christmas ahead (feat.Chundung) (미리 메리 크리스마스 (feat.천둥 of MBLAQ))IU40rank/position
IU’s irresistibly sweet winter love song.
It sings about being able to stay close to your lover and walk side by side, and how happy being in love has made you.
With Christmas fast approaching, her love for her partner is deepening even more.
On Christmas Day, she’ll stay by their side the whole time.
That single-hearted devotion to the one she loves makes your heart flutter.
