“Why'd you do that to me” is a minimalist heartbreak ballad sung from the depths of pain.
A woman, wounded by a man’s cruelty, sings with a voice so transparent it feels like it could vanish in the wind.
The melody is stripped down, almost fragile—just enough to carry the weight of her sorrow.
This is the sound of a muse, no longer trying to impress—just to feel.
The master of ballads continues their evolution, choosing simplicity to express purity, sadness, and the silent strength of survival.

Let the echo of her broken voice linger in your heart.

Frosutissimo （Golden Week Special Remix）

"NEXT // TIME" is a pure electronic odyssey—driven by futuristic energy and a sense of revelation.
With shimmering synths, layered beats, and a pulse that feels both sacred and digital, this track explores the dawn of a new era.
It’s not just a song—it’s a message from the future. Let your spirit ascend through rhythm and prophecy.



NEXT // TIME

"Mandelbrot Set" is an epic, symphonic-scale electronic composition — a journey through evolving sonic fractals, where each phrase transforms beautifully and powerfully into the next.

Like the mathematical marvel it’s named after, the track is ever-shifting and infinite in its detail. Bold arpeggios rise and fall like digital waves, shimmering pads spiral outward like fractal tendrils, and rhythmic pulses draw the listener into a hypnotic loop of beauty and complexity.

🔍 What is the Mandelbrot Set?
The Mandelbrot Set is a famous set of complex numbers in mathematics, defined by the equation z → z² + c. When visualized, it produces intricate and infinite fractal patterns. It’s a symbol of mathematical beauty, complexity, and self-similarity at every scale — and this track pays sonic tribute to that very concept.

This isn’t just a song. It’s a digital symphony for the mind — a universe of sound unfolding in fractal elegance.



Mandelbrot set

A deeply personal piano concerto born from love, loss, and unwavering devotion.
This piece was written in one emotional surge after the composer's beloved black cat suddenly lost her sight. It is a musical declaration: even when vision fades, the dignity of life, the right to joy, and the pursuit of happiness remain unshaken.

In the swelling middle section, listen for the surging trot-inspired passage — a life-force bursting forth.
It expresses a vow to stay together forever, through every darkness and light, carried by infinite love.
This is more than music — it’s a cry from the soul to honor all life, seen or unseen.

Let this piece remind us:
"Feeling is seeing."



I Cannot Hear, I Cannot See, I Cannot Speak, But I Feel Everything

Don’t be fooled by the name — Electric Ballad isn’t a slow jam.
It’s a high-energy girls’ electro dance anthem that bursts with power, rhythm, and pure sparkle.

Blending shimmering synths, fierce beats, and an unapologetically vibrant spirit, this track is made for moving.
It’s a celebration of freedom, confidence, and electrified emotion — a sound that glows as bright as neon and hits as hard as a heartbeat.

Turn it up, feel the rush, and let your soul dance.

Electric Ballad

"Life Could Be a Dream" is a heartfelt anthem to life itself — a celebration of existence in its purest form. Built around minimal instrumentation and almost entirely vocal in arrangement, the track features a soaring, angelic voice that evokes both tenderness and strength.
This song is a tribute to the beauty of simply being alive, and a gentle encouragement to every soul walking their unique path.
Let the simplicity and sincerity of the harmonies remind you that even in quiet moments, life can be a dream.



Life Could Be a Dream

“Million Lights Ablaze” is not bound by genre — it’s an aria, an epic, an electronic odyssey.

This piece moves through phrases and melodies that have long remained untouched — unearthed and reimagined with intention.

An experimental yet inevitable progression, it walks between beauty and intensity, silence and ignition — like a million lights set ablaze in the night sky.

Created to challenge form and expectation, this is a song born of freedom, curiosity, and necessity.

🎶 Written, composed, and produced by rosu.

Million Lights Ablaze

“Pretty Chaos” is a neon-burning blast of girl-punk energy — wild, anarchic, and unstoppable.
A hyper-pop sprint that crashes through the night with electric riffs, junkyard fire, and a queen who thrives in madness.
It’s loud, messy, and unapologetically free — a 90-second rebellion where chaos isn’t ugly, it’s beautiful. Turn it up, let it burn, and scream along.

Pretty Chaos

Last year I got lazy and ended up rushing a Christmas album in just two weeks — lesson learned.
This time, I’m starting early, and here comes “You always said it was all in my head”: a sad ballad born from reflection, regret, and fragile hope.
But don’t mistake the humor in its backstory — the song’s value is real. One listen, and it might touch your heartstrings forever.

You always said it was all in my head
