RIIZE Drops ‘Insomnia’: Why Their First Acoustic Pop Track Proves They’re K-Pop’s Most Versatile Rookies

If you’ve been following K-Pop over the last couple of years, you already know that RIIZE doesn’t really do predictable. Ever since burst onto the scene with Get A Guitar, Shotaro, Eunseok, Sungchan, Wonbin, Sohee, and Anton have carved out their own unique corner of the industry by leaning heavily into what they call “emotional pop.”

They gave us funky grooves, nostalgic R&B-infused tracks like Love 119, and high-energy stadium anthems that had fans dancing in unison. But just when you thought you had their sound pegged down, they dropped a brand-new surprise that completely flipped the script.

Enter “Insomnia”

Released as a special prologue single ahead of their massive upcoming second full-length album, “Insomnia” is RIIZE’s very first official acoustic pop track. If you haven’t listened to it yet, grab your favorite pair of headphones, get comfortable, and let’s dive into why this late-night ballad is a turning point for the group—and why it’s currently dominating our late-night playlists.

A Late-Night Soundtrack: The Vibe and Production Behind “Insomnia”

Let’s be honest: we’ve all been there. It’s 2:30 AM, the house is dead silent, and your brain decides it’s the absolute best time to replay every awkward conversation you’ve had since 2018. That exact feeling of restless, quiet exhaustion is captured flawlessly in RIIZE’s “Insomnia.”

Unlike their previous upbeat title tracks, this song strips away the heavy synths, driving basslines, and fast-paced percussion. Instead, it’s built around a warm, lyrical, guitar-driven melody that feels intimate and raw.

Behind the scenes, the track boasts some heavy-hitting global star power. It was crafted in close collaboration with the renowned American production team The Stereotypes alongside composer August Rigo—a dream team that previously worked with RIIZE on 9 Days. Together, they managed to blend a classic acoustic singer-songwriter feel with modern K-Pop production polish, creating something that sounds universally comforting yet distinctly RIIZE.

Kim Eana’s Lyrical Magic: Turning Sleepless Nights Into Poetry

No great acoustic track is complete without lyrics that cut right to your soul, and RIIZE hit the absolute jackpot here. The group teamed up with legendary lyricist Kim Eana—the creative genius behind some of K-Pop’s most iconic tracks, including IU’s Good Day.

Kim Eana’s penmanship shines through the gentle melancholy of the track. The lyrics trace the winding, looping thoughts that flood your mind when you’re thinking of someone special and the clock keeps ticking past midnight. There’s a vulnerable honesty in the way the lines address sleeplessness and lingering affection. It doesn’t try to offer a neat, happy ending; instead, it sits comfortably in that bittersweet, lonely feeling, making it the ultimate companion for autumn and winter nights.

Stepping Off the Stage and Letting the Vocals Do the Talking

RIIZE has an unshakable reputation as live performance powerhouses. Whether they’re tearing up the stage at mega-music festivals or dropping choreography practice videos that look effortlessly sharp, their physical performance level is top-tier.

However, “Insomnia” shifts the camera angle entirely. By moving away from heavy choreography, the spotlight is pointed directly at their vocal maturity.

Over the last year or so, fans have watched (and listened) as each member’s vocal stability and emotional delivery have grown exponentially. In “Insomnia,” that growth is on full display.

• Sohee and Anton handle the delicate high notes and emotional runs with a tender fragility that feels incredibly personal.

• Wonbin and Sungchan deliver rich, textured mid-tones that anchor the melody.

• Shotaro and Eunseok add gorgeous harmonic layers that weave the whole track together.

The group has also been rolling out stripped-down, cozy live content—think the boys sitting on a couch with a single acoustic guitar, singing live without any backing tracks or heavy vocal processing. It’s refreshing, it’s authentic, and it proves that RIIZE doesn’t need pyrotechnics or flashy sets to sound incredible.

The Road to 2027: Setting the Stage for Their Second Studio Album

If you’re wondering why RIIZE is pivoting to a soft acoustic vibe right now, look at the bigger picture. “Insomnia” isn’t just a random drop to keep fans fed; it’s officially a prologue single paving the way for their second full-length studio album, slated for release in the spring of 2027.

Coming hot on the heels of their record-breaking second mini-album II—which safely added another million-seller badge to their growing trophy case—this acoustic shift is a bold strategic move. It tells the K-Pop industry that RIIZE isn’t content with just doing one thing well. They are actively expanding their musical spectrum, proving they can pivot from upbeat dance tracks to sensitive, mature singer-songwriter pop without missing a beat.

It’s the kind of artistic risk that separates standard rookie groups from generational icons in the making.
