This is a song about the sorrow of heartbreak, played with an intense rock sound.

If you’re not here, I’ll lose even the will to live.

It expresses that kind of straightforward emotion.

While the sound is exhilarating, there are also moments that feel almost mad, giving the song a deep, complex tone.

I Ended Up Missing You – Pote / Hatsune Miku, Kagamine Rin [MV]
I’ve started to miss you so much, poutey.

It’s an airy, light-hearted tune that makes you want to jump up and run as you listen.

It’s a narrative piece about an alien living on Earth and working like an ordinary human who starts to feel homesick for their home planet… but in reality… Well, I’ll let you discover the twist yourself.

There’s a touch of bittersweetness, but overall the song keeps a comical tone, so it’s sure to lift your spirits.

This is a song by Kanzaki Iori, with Kagamine Len’s squeezed-out, heartrending vocals piercing the heart.

Released in July 2020, it portrays the complexity of human relationships and the emotions hidden deep inside.

The true self concealed by putting on airs, the desire to be loved, and the loneliness—these feelings are packed into the lyrics, tightening my chest every time I listen.

It’s a track you’ll want to listen to alone in your room, especially on a night when your heart feels a little lonely.

Colchicum is tiresome

A stylish Vocaloid rap whose soft acoustic guitar tones gently shake your eardrums.

Created by the Vocaloid producer Kedarui, known for hits like “Heartbreak ≒ Blues,” it was released in 2019.

Although it’s introduced as a Vocaloid rap, the chorus is built around a catchy melody.

In other words, it’s a track I can recommend even to rap beginners.

Children's Paradise / Sadoya feat. KAFU
Children's Paradise Sadoya

The gap between the title and the song just gets me.

It’s a track by Vocaloid producer Sadoya, released in October 2022.

Every timbre feels ominous, perfectly matched with KAFU’s noise-tinged vocals.

I imagine many people love this dark, heavy, frightening mood.

The eerie MV, which blends illustration and live-action footage, adds even more depth to the worldbuilding.

I want to see something scary.Shannon

MV 'I Want to See Scary Things' / Shannon feat. GUMI
Shannon who wants to see something scary

Since beginning activity as a Vocaloid producer in 2017, Shannon—a multi-creator who also handles their own illustrations and videos—has crafted this track.

Its ominous lyrics, set to a sprightly, childlike melody reminiscent of a nursery rhyme, stir a sense of fear.

The uniquely inorganic timbre of VOCALOID vocals meshes uncannily well with the guileless melody, further shaping the song’s distinctive world.

It’s scary yet irresistibly replayable—a truly addictive number.
