■ BBoom BBoom - Ultra-Dense Funky House with Bold Sound Layering and Explosive Energy by MOMOLAND

MOMOLAND's "BBoom BBoom" is an Expert-difficulty track set to a cheerful 126 BPM tempo, notable for its bold sound arrangement that transcends the conventions of dance pop. Co-written by Shinsadong Tiger and Beom x Nang and produced by Shinsadong Tiger, this track draws the listener's auditory attention with the acoustic guitar strokes at the intro, then immediately drops in powerful percussion and exaggerated synth-brass themes, driving the track's density to its absolute limit.
Using the stable vocals of main vocalists Taeha and Jane as stepping stones, the energetic ad-libs of all the members and the onomatopoeic word "BBoom BBoom" itself act as a rhythmic sound texture, prompting the listener's intuitive physical reaction. In particular, while maintaining the steady drive of Funky House, the track features a surprise Trap/Hip-hop breakdown in the second verse, delivering unpredictable variations and an intense sense of immersion for rhythm players. Even with the densely intersecting individual audio elements, the sound design—where they never mask one another and instead race forward on the exact same trajectory of excitement—makes players physically experience exceptional impact and consecutive note thrills on the Mstar stage.

■ FACE - A Timeless Message Condensed with Intense Dubstep Drops and Sharp Teenage Passion by NU'EST

NU'EST's "FACE" is an authentic electronic dance track that broadens the category of K-pop electronic music by combining Dubstep and Electro Pop sounds within a heavy 124 BPM tempo. Written by Swedish composer Daniel Barkman and arranged by Lee Yoo-jin, this work delivers the social message of school violence straightforwardly and sincerely from a teenager's perspective, securing both auditory solemnity and narrative weight.
The gritty, bold tone of main vocalist Baekho and the refreshing vocal lines of Minhyun and Ren create an exquisite contrast. Rather than stretching vocals into a single long melody, the track transforms them into part of the rhythm section through short, chopped staccato methods and repetitive English phrases. The raw texture of the synth bass that explodes as it enters the chorus and the heavyweight drop rhythm characteristic of dubstep form a cascading waterfall of notes on the rhythm game stage, delivering raw catharsis to the player's fingertips.

■ HWEEK - A Refreshing Midsummer Swing of Escapism Led by Cheerful Brass and Groovy Bass by TEEN TOP

"HWEEK," introduced by TEEN TOP after re-forming into a four-member lineup, is an Expert-difficulty Funk Pop track based on a fast 137 BPM rhythm designed to blow away daily fatigue and stress in an instant. Completed with lyrics by Seo Ji-eum and composition and arrangement by Josef Melin, this track features a sharp, exhilarating brass section that refreshingly cuts through space right from the start, underneath which a resilient fingering bass and cheerful guitar strokes support the backbone of the groove. Combining Niel's signature sweet falsetto/soft vocals with the clean vocal placements of Chunji, Ricky, and Changjo, it creates a light and springy texture, while utilizing ad-libs and short syllable repetitions like snare percussion to accelerate the momentum of the rhythm.
Rather than engaging in a turf war, the brass performance and vocals smoothly intersect and lead each other's empty spaces, delivering the feeling of perfect rest and free escapism riding along fluid slide notes on the Mstar stage.

■ Who is she - An Aura Flaunted with Millennial R&B Pop's Heavy Bass and Laid-Back Narrative by KISS OF LIFE

KISS OF LIFE's "Who is she" is a sensual track that modernly reinterprets the sensibilities of millennial-era R&B dance pop over a 134 BPM beat. Composed by Slush Puppy, Austen Healey, Rollo, and Sophia Brenan, with arrangement by Strawberrybanana Club, this track is grounded by a solid sub-bass in the low end and rhythm instruments that center the entire song. The fusion of Belle's high-note skills, Natty and Julie's groovy vocals and rap, and Haneul's neat tone directly conveys a confident attitude and ease where the vocals do more than just hit notes—they dominate the stage.
Based on an underdog narrative of forging one's own trajectory rather than being trapped in others' frames and regulations, it emphasizes provocative and sophisticated pacing of breath over explosive high notes. The solid low-end bass and the punchiness of the electronic sounds imprint an irresistible groove weight onto individual players as the on-beats and off-beats of note play intersect.

With members Jinjin, MJ, Moonbin, and Rocky directly participating in lyric writing and rap making, alongside top-tier overseas producers like Jes Meinertz, this track creates organic synergy through a rhythmical retro funk bassline, snappy drum rhythms, and refreshingly blooming synth lines.
MJ's exceptional high notes, the warm vocals of Cha Eun-woo, Yoon San-ha, and Moonbin, and the sensible raps of Rocky and Jinjin combine to create a gentle sweetness that brings a smile to the face without artificially squeezing out emotions. Even amidst the upbeat and joyful energy, a solid disco bass keeps the center grounded.
