FOR YOUBTS

FOR YOUBTS

This Japanese version of the song released by BTS in 2015 expresses feelings toward someone precious who is far away.

Whether it’s a long-distance relationship or friends separated due to work or family circumstances, don’t we all have at least one or two people we wish we could see and spend time with every day but can’t? Even when apart, we remain connected at heart—this song carries that beautiful message.

L5ST is a boy group drawing attention as a fresh new force from Korea.

Released in December 2024, this work is an ambitious piece that showcases the group’s individuality.

Their musical world—woven from powerful vocals and dynamic instrumentation—grabs listeners and doesn’t let go.

The lyrics convey a passion for freedom and self-expression, and the song’s strength feels like it can help you forget the fatigue of everyday life.

The music video also seems to be earning praise for its high quality.

It’s a perfect track for those who value staying true to themselves or are seeking a new musical encounter.

Expectations are high for L5ST’s future activities as well.

친구해(BeMyFriend)주헌(JOOHEON) from MONSTA X

A friendship song by MONSTA X’s two rappers, Joohoney and I.M.

If you’re a K-pop fan, you’ll probably recognize the meaning of the title “Chingu-e” right away.

Chingu means “friend,” after all.

It carries the sense of “let’s be friends,” with a party vibe that says, forget the complicated stuff—let’s just have fun together.

The casual, everyday feel—like in Western music videos—also suits the mood of the song really well.

Girlfriendi-dle

Girlfriendi-dle

A track that leaves a strong impression with its rhythmic electropop sound.

It’s included on their eighth mini-album, “We are,” released in May 2025.

Leader Soyeon handled both songwriting and composition, crafting a piece with the kind of powerful messaging characteristic of (G)I-DLE.

The driving beat and energetic sound intertwine with the members’ distinctive vocals, gripping listeners from start to finish.

The lyrics, which express women’s independence and strength, are also striking, giving the song an anthemic quality that encourages those who struggle to feel confident in their own path.

In the music video, each member is portrayed confronting her inner self in a dreamlike way, offering plenty of visual intrigue to enjoy.

Billlie is a girl group that made their Japan debut in 2023.

Active across platforms like YouTube and Instagram, they sing “BYOB (bring your own best friend),” a song that carries a straightforward message to friends.

BYOB is widely known overseas as an initialism used on party invitations.

By replacing the last “B” with “best friend,” the song conveys the message, “Bring your best friend to the party.” It’s K-pop with an urban vibe, featuring airy, expanding synth tones.

Graduation Day (졸업하는 날 / The Day of Graduation)IU

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.

aespa’s new song portrays friendship and bonds in the digital age.

It’s striking how young people’s hearts connect through fun chats that go on until late at night.

The lyrics, sprinkled with social media slang and hashtags, feel modern and relatable.

Included on their first full album, “Armageddon,” released May 27, 2024, the track conveys the warm bonds forged through online communication.

The colorful, humor-filled music video is also a highlight.

It’s a heartwarming song that makes chatting with friends even more fun.
