IU’s Most Popular Songs Ranking [2026]

Lost ChildIU21rank/position

IU(아이유) _ Lost Child(미아) _ MV

This song is IU’s debut track from 2008.

It may surprise you, but she was in her third year of middle school at the time! To have this level of vocal ability and expressiveness as a ninth grader is astounding.

It’s not just her cuteness—her sheer talent explains why she was loved by people of all ages and genders as the “Nation’s Little Sister.” She handled everything herself—vocals, chorus, even aria—and all I can say is, it’s incredible.

Merry Christmas In AdvanceIU22rank/position

191116 아이유(IU) – 미리 메리크리스마스 (Merry Christmas in Advance) 직캠 @ Love, Poem 부산 콘서트 앵앵콜 [4K 멀티캠]

The sparkling, beautiful sound and lively tempo make my heart bounce.

The sampled Jingle Bells in the middle is so fun too! IU’s high-tone voice and the lyrics overflowing with happiness are absolutely heart-fluttering, right? It’s the ultimate Christmas song where her maturing, elegant direction and her cuteness are perfectly balanced.

It’s included on her third mini album “Real,” released in 2010.

Our Happy EndingIU23rank/position

IU (아이유) – Our Happy Ending (Hotel Del Luna Special OST) Lyrics (Han/Rom/Eng/가사)

It’s the ending song from the IU-led drama Hotel Del Luna—a very lovely ballad, though unfortunately it hasn’t been officially released.

The song carries the wishful thoughts of “What will become of the two lovers’ ending?” and “I hope it won’t be a sad one.” IU’s voice slips straight into your heart, as if a close friend were singing right beside you.

This song has that same charm.

ShopperIU24rank/position

IU ‘Shopper’ MV

A track from IU’s sixth mini-album “The Winning,” released in February 2024, stands out with its retro electropop sound and her bright, expressive vocals.

The lyrics, which depict boundless desire and the endless pursuit of it, convey the importance of chasing the dreams you had as a child without trampling on them.

The music video, with a worldview reminiscent of a fantasy film, is also a highlight.

Showcasing a new side of IU, this song is a great recommendation for those just getting into K-pop.

Beautiful DancerIU25rank/position

IU – Beautiful Dancer

This is the lead track from her first Japan-original mini album, released in 2013, “Can You Hear Me?”.

It’s a song where you can fully enjoy the world of IU, from the lead vocals to the backing harmonies.

Not only does it showcase IU’s beautiful singing voice, but she also recites a poem in Japanese at the beginning.

That part is wonderful, too!
