IU’s Most Popular Songs Ranking [2026]

하루 끝 (Every End of the Day)IU29rank/position

[MV] IU (아이유) – ‘하루 끝’ (Every End of the Day) [HD]

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

[MV] IU(아이유) _ Twenty-three(스물셋)

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.

NaggingIU & Seulong31rank/position

IU&Seulong – Nagging, 아이유&슬옹 – 잔소리, Music Core 20100626

IU is one of South Korea’s leading songstresses.

Her name is pronounced just as it’s written: Eye-You.

Since she’s also released Japanese-language songs, many of you may already be familiar with her music.

One of her classic collaborations is “Nagging,” performed with Lim Seulong from the popular boy group 2AM.

The two are known for their close friendship, and this track showcases the seamless, rich harmonies that arise from their rapport.

It’s a dramatic yet cute song—highly recommended if you’re in love.

Autumn MorningIU32rank/position

Autumn morning (가을 아침)

When I just want to enjoy nothing but IU’s pure, gentle voice, this is unquestionably the song.

It draws you to IU’s brilliance as a songstress and her cute, soft charm as the Nation’s Little Sister.

A remake of a lullaby, it’s a heartwarming track that seems to gently fill your mind with family and nostalgic memories.

IU’s ability to deliver such a simple song—either a cappella or with tender acoustic accompaniment—with such impeccable perfection is truly impressive.

Not Spring, Love, or Cherry BlossomsHIGH4, IU33rank/position

[MV] HIGH4, IU(하이포, 아이유) _ Not Spring, Love, or Cherry Blossoms(봄,사랑,벚꽃 말고)

Even though the cold winter has passed and the warm season has arrived, there’s still a loneliness lingering in the heart… It might be perfect for indulging in that bittersweet mood of spring.

This is a collaboration between the male idol group HIGH4 and singer-songwriter IU, included on the mini-album “HI HIGH” released in 2014.

The gentle vocals entwined with the relaxed rhythm and melody linger in your ears.

If you listen when you want to put a period on a past romance, it might just stay close to your feelings.

Palette (Feat.G-DRAGON)IU34rank/position

[MV] IU(아이유) _ Palette(팔레트) (Feat. G-DRAGON)

This is the title track from IU’s fourth album, Palette, released when she turned 25.

With her colorful charm, IU seems to look at herself at that moment and think, “This is who I am,” and “These are the things I like.” IU’s whispery, cute vocals, along with BIGBANG’s G-DRAGON delivering a rap like an older oppa speaking to her, add a great touch.

Twenty-five—somewhere between grown-up and still young.

Many people will likely relate to IU’s honest, down-to-earth feelings.

Rain DropIU35rank/position

[IU] Rain Drop & Heart (마음) Concert Live Clip (@ 2017 Tour ‘Palette’)

The “raindrop” in the title refers to a drop of rain.

The word has a cute ring to it, and describing those raindrops as “the sky is crying” perfectly matches IU’s adorable image.

The song expresses a bittersweet feeling toward a lover she can no longer meet.

Don’t miss IU’s clear, soaring high notes in the chorus!
