김세정(KIM SEJEONG) ‘태양계’ Official M/V

Kim Sejeong, who first rose to fame as a member of gugudan and is now beloved for both her acting and singing, released the single album “Solar System” in December 2025—a work that deeply resonates with the sensibilities of winter.

This release is a remake of one of Sung Si-kyung’s signature ballads, arranged by guitarist Jeok Jae, who breathes new life into the piece while preserving the lyricism of the original.

The lyrics poignantly liken the habits that linger after a breakup to the orbits of planets revolving around the sun.

With restrained, acoustic production, the sound blends seamlessly with her delicate vocals, echoing like an intimate soliloquy.

It’s a song that will gently accompany quiet nights spent alone in contemplation.

365 Days

A deeply moving ballad sung by Lee Changsub, the main vocalist of BTOB.

Released in December 2025, this track is a collaborative piece with the film “Even If This Love Disappears from the World Tonight.” The original song, released by singer Ailee in 2011, is a classic that likens the pain of parting to the passage of time.

It conveys the desperate feeling of wanting to forget but being unable to, and Changsub’s delicate yet powerful voice intertwines with the lyrics’ worldview to striking effect.

The arrangement is emotionally crafted to mirror the film’s story, making it an irresistible choice for those who want to linger in the afterglow of the narrative.

As the cold deepens, it’s also a song that gently stays by your side when you want to quietly heal your heart.

MINHO 민호 ‘TEMPO’ MV

A sophisticated dance track where groovy 808 bass intertwines with a variety of percussion.

It’s the title song from TEMPO, the first single album released in December 2025 by Minho, a member of SHINee who debuted in 2008.

The song carries a message about closing the distance at the pace the other person desires, conveying a mature ease and kindness without being pushy.

After his 2024 full album CALL BACK, his refined expressiveness is even more impressive.

Within the cool sound, his vocals radiate warmth—and that contrast is just unbeatable.

It’s a must-listen for night drives or for adults looking to spend a relaxed, unhurried time.
