[Latest] Fast-tempo Melo & Rapid-fire Vocaloid Songs Special [Classics] (41–50)
LokiMikito P
This tongue-twisting melody is strangely irresistible—you start wanting to sing it yourself! “Roki,” by the popular Vocaloid producer Mikito-P, was released in 2018.
It’s a rock tune with a brisk rhythm, crisp guitar riffs, and a cool slap bass.
It makes you want to jump and groove along.
The song is a duet between Kagamine Rin and Mikito-P himself, which makes the call-and-response parts especially fun.
If you get the chance, definitely try singing it at karaoke.
Cute Girlfriendsyudou
It’s a yandere song that hits you with fear and cuteness at the same time.
Created by the Vocaloid producer syudou—also known for writing and composing Ado’s smash hit “Usseewa”—the track was released in 2021.
The wavering vocals and sound, along with the MV’s dangerous atmosphere, offer plenty to get hooked on.
Why are we so drawn to that sickly, unhinged vibe? Be sure to listen to the answer song “Kareshi no Jude” as well.
Machinegun Poem DollcosMo@bousou P
cosMo@Bousou-P, famous for the insanely fast-tongued song The Disappearance of Hatsune Miku.
His Machine Gun Poem Doll is a track whose appeal lies in hyper-speed phrases that make you think no human could possibly sing it.
This song was written as the first-anniversary theme for the mobile game Project Sekai, and its cute vibe that reflects the project’s worldbuilding is absolutely irresistible.
At the same time, the part where the bass drum pattern syncs with the vocals barrels forward at an astonishing speed, delivering overwhelming impact!
New BreedMarashii × Jin × Horie Shota (kemu)
A major collaboration in the Vocaloid scene has become a hot topic! A gem of a track created by pianist Marasy, Jin (Shizen no Teki-P), and kemu (Shota Horie).
Released in April 2023, this work proudly took 1st place in the VOCALOID Collection 2023 Spring TOP 100.
The playful lyrics and catchy sound are a perfect match, and Kagamine Rin’s crisp vocals pair beautifully with it.
Don’t miss the sly commentary on modern society delivered over an irresistibly groovy beat!
I’m not mentally unstable!isana
“I’m Not a Menhera!” is a song whose addictive charm comes from the contrast between its fierce metal sections and cute pop parts.
It’s uniquely structured like a duet: Hatsune Miku handles the main singing parts, while Otomachi Una takes on the rapid-fire spoken lines.
In particular, the must-hear moment is right after Una spits out a fierce, toxic line and it flows into Miku’s slow, waltz-like phrase.
The dynamic arrangement is downright astonishing.
When your heart feels heavy, blast away the bad vibes with this flashy track!
I am not a robot.piinata
This is a track that shines with an ironic worldview, built around the familiar internet security check phrase, “I am not a robot.” Created by Pīnata and released in October 2025, it uses EDM sounds and Kasane Teto’s vocals to vividly portray a message laced with satire toward internet culture and mechanical authentication systems.
It reflects the true feelings and façades of those of us living in a digital society.
Be sure to experience these waves of sound for yourself!
Retry!hiroki
A high-speed tune that forces a choice between two options.
Released by hiroki.
in October 2025, this track features twin vocals by Hatsune Miku and Kasane Teto.
The repeated question “Which will you choose?” riding over a driving dance beat becomes irresistibly catchy.
Highly recommended if you’re looking for addictive Vocaloid tracks! If you get hooked, be sure to check out the previous work, “Which Will You Choose?” as well!
