Monsta X Releases Bittersweet Ballad ‘Baby Blue’

Monsta X, the “beast idols,” are back with “Baby Blue,” but this time they trade in their signature sound for a slower burn of quiet intensity.

For Monsta X, 2025 has been very special, as after over two years of mandatory military service keeping them apart, all the members—Shownu, Minhyuk, Kihyun, Hyungwon, Joohoney, and I.M.—finally reunited, and just in time for their 10th anniversary.

Commemorating the moment, the K-pop icons released the compilation album Now Project Vol. 1, followed by the digital single “Do What I Want,” their thirteenth EP, The X, and now their English single, “Baby Blue,” adding a new chapter to their music, their story, and their journey together.

Speaking of the newest, “Baby Blue” is apparently for Monbebe’s (Monsta X’s fandom name) around the world and for anyone who has a thing for love ballads. And because it’s entirely in English, the song’s nostalgia and its emotions definitely resonate a bit more. Very easy on the ears, “Baby Blue” flows with smooth synths, beautiful melodies, and, of course, Monsta X’s emotive vocals, recalling memories and reminding you of love’s bittersweet farewell.

The lyrics subtly narrate the story of love that’s fading like a Polaroid picture. “You dance like I remember, baby “blue”—the lyrics cut deep, evoking the memories of love that’s lost now. It’s a feeling we’ve all been through, right? This wistfulness persists within you even after you’ve moved on. Lines such as “Are we living in the past? Just so we can make it last…” expresses that longing and that resignation that define this emotional essence.

Musically, “Baby Blue” is a beautiful addition to their previous English releases, including “Who Do U Love?” (feat. French Montana), “Middle Of The Night,” “Play It Cool” (with Steve Aoki), and “You Can’t Hold My Heart,” while also speaking to Monsta X’s evolving sound. The song’s calm yet confident tone, layered with delicate R&B and electronic sounds, is like a balanced mix of fire and ice, a jam that you listen to and say, “This one’s lit.”

The music video is a visual mise-en-scène of black and blue and subdued colors, underscoring the ache and sentiments while symbolizing a rite of passage – one of change and rebirth. The theme of “Revival” resonates throughout, with fragments of blue light and scenes dissolving into brightness, reflecting the wounds of farewell and the quiet renewal that follows. It’s a stunning cinematic display of the song’s theme as well as Monsta X’s creative vision and narrative depth.
