IU’s Most Popular Songs Ranking [2026]

Our Happy EndingIU22rank/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.

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.

People Pt.2Agust D, IU24rank/position

Agust D ‘사람 Pt.2 (feat. 아이유)’ Official MV

Suga, a member of the seven-member boy idol group BTS.

His solo release as Agust D, “People Pt.2,” is a cool number featuring IU, a hugely popular singer-songwriter in Korea.

The medium-tempo, R&B-like track pairs beautifully with Agust D’s impressive vocal prowess as he switches between rap and singing—it’s truly moving.

Adding IU’s vocals enriches the song even further, giving it an even more nuanced and flavorful atmosphere!

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!

Winter SleepIU27rank/position

[IU] ‘겨울잠 (Winter Sleep)’ Live Clip

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.
