It’s a lively funk track with a satisfying wah-infused guitar and a roaming bassline.
Created by Nejishiki, whose deep musicality is highly regarded by overseas Vocaloid fans, it was released in March 2023 and participated in the TOP100 category of Vocalo Collection (VocaColle) Spring 2023.
The big band-style, glittering sound is absolutely wonderful! Following each element—the horn section, the bouncing piano—is a joy.
Yet the lyrics express a bittersweet message of love, and that contrast really gets you.
Love is surely skyrocketing☆noboru↑P

According to the creator, it’s a track that “turned into idol pop somehow while I was trying to make death metal.” Indeed, it’s so adorably charming that it’s hard to believe it was ever meant to be death metal, and just listening to it lifts your spirits.
It’s uptempo, sparkly, and guaranteed to hype you up—truly “pop music by an idol,” plain and simple.

This is a work written and composed by Hari-P that sings of a heartrending farewell.
It is also a related song to the novel “We Quietly Kissed,” published by PHP Institute under the name Tsubasa Harihara.
A melody played during breaks in writing the novel and the protagonist’s feelings came together to form this song as a single piece.
With elements like the novel’s title appearing in the lyrics, it’s an irresistible track for fans who know the story!
Hello / Goodbyeburiru

This piece was announced on the release day of “Synthesizer V AI Kasane Teto.” It’s a song by the Vocaloid producer Brill—also known for tracks like “Secret Police” and “I Don’t Care!”—titled “KONNICHIWA/SAYONARA.” The relaxed tempo carries a subtle darkness that pairs well with Teto’s mature singing voice.
The lyrics, which bid farewell to someone precious who can never be met again, are heart-wrenching.
The more you listen closely, the more depth it reveals—a Teto song that grows on you with every spin.

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

I ended up missing you.pote

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

There’s a touch of bittersweetness, but overall the song keeps a comical tone, so it’s sure to lift your spirits.
More than that, it’s the kind of Vocaloid track that makes you think, “Let’s do our best together!”
