Vocaloid Birthday Celebration Songs (1–10)
Birthday songone hundred

A birthday song that opens with a catchy vocal melody carried by a transparent-sounding performance: the shimmer of acoustic guitar, a lingering bassline, and richly layered strings.
It’s a track said to have been made so the artist could be celebrated on their own birthday, and knowing that gives the song a whole new perspective when you listen.
The gentle atmosphere that permeates the entire piece makes it a perfect fit for birthdays—whether for yourself or for someone else.
Chronic back pain, four-on-the-floorNamiguru

This song features a sound with elements of Latin jazz, sprinkled with humor.
It’s a work by Vocaloid producer Namiguru, included on the compilation album “4UNREAL 2REAL,” released in January 2025, with its music video published on April 1 to coincide with Kasane Teto’s birthday celebration.
The warm tone of the upright bass and Teto’s calm vocals leave a strong impression.
The snappy melody that rhymes “koshitsū-mochi” (back-pain sufferer) with “yotsu-uchi” (four-on-the-floor) has a charm that makes you want to sing along as you listen.
Grape-colored IntoxicationKashii Moimi

A bewitching Vocaloid track woven from a fantastical worldview and decadent expression.
It’s a song by Vocaloid producer Moimi Kashii, released in February 2025 to coincide with KAITO’s birthday celebration.
Lyrics interlaced with love, desire, and inner conflict seep deeply into the listener’s heart.
The gothic soundscape and KAITO’s mature vocals are absolutely superb.
Once you listen, you won’t be able to stop imagining the story between “you” and “me.”

Facade QuestionSatsuki

This is a Vocaloid song woven with deep insights into modern people who hide their true selves.
Composed by the Vocaloid producer Satsuki, it was released in April 2025 to coincide with Kasane Teto’s birthday.
It’s Satsuki’s contribution to “Pokémon feat.
Hatsune Miku Project VOLTAGE High↑.” In a duet between Hatsune Miku and Kasane Teto, the lyrics portray a world where fiction and reality intermingle, conveying the pain of living behind a mask and the way things born from falsehood can transform into truth.
Be sure to listen for the high-speed musical development as well.
HAPPY BIRTHDAY☆tetra marriage P

This is a song created as a birthday song for its creator.
It’s a work by KOOSAN, also known as Quadruple Marriage P, released in 2010.
The piece has a somewhat wistful electronic music vibe.
Originally there was only a GUMI version, but a miki version and a twin-vocal version were later made as well.
The lyrics are filled with celebratory messages from the VOCALOIDs.
If you’re feeling lonely spending your birthday alone, listening to it might take your mind off things.
Kowloon Stray DogMiyamori Literature

The Chinese-style rock sound is insanely cool! Released by Bungaku Miyamori in December 2024, this track is a celebratory number commemorating the 17th anniversary of Kagamine Rin and Len.
You’ll be enchanted by the oriental world woven by the twins’ harmonies.
The sharp, edgy arrangement pairs perfectly with the highly narrative lyrics that conjure up scenes of a bustling city.
If you’re looking for a hard-hitting song, be sure to check it out!
The Legend of the Facing MirrorsAkane Yomitan

This is a Teto track that draws you into a suspicious, eerie atmosphere.
Created by Akane Yomitan, it was released in April 2025, timed with Kasane Teto’s birthday celebration.
Based on the urban legend of the “facing mirrors,” its horror-laced worldbuilding and slightly shadowy tone are incredibly addictive—you’ll find yourself listening on out of a thrill-seeking curiosity.
The high-quality animated MV is another highlight.
Give it a listen once, and you’ll be hooked.
