Can you sing these? A selection of difficult and fast Vocaloid songs (41–50)

Hardcore daydreamerdainamikku jien zu

If you want to sing a high-energy song, this one’s for you—Dynamic Jienzu’s “Yumemi Gachi-zei” might be perfect! Released in November 2022, this track is a blast from start to finish, with relentlessly high-tension sound and vocal work.

It makes you want to crank the volume way up.

The lyrics, which sing of the passion for chasing dreams, are also memorable.

Be sure to capture that upbeat vibe with your vocals!

Jugemububuzera

Jugemu / Vuvuzela ft. Seikai
Jugemububuzera

This work, released by Bubuzera in December 2023, is inspired by the rakugo piece “Jugemu.” Its standout feature is lyrics composed solely of the extraordinarily long name that appears in “Jugemu.” By switching musical genres between parts, it presents a multifaceted take on “Jugemu.” You might get a sense of the freedom of “expression” from this song.

It’s killing two birds with one stone—why not give it a try as if you were memorizing rakugo?

A rare predation scene of the Scorpion GirlSTEAKA

Let’s turn up the volume and enjoy some hardcore electronic music! This track by Vocaloid producer STEAKA was released in 2022.

It placed 5th in the “VocaColle 2022 Autumn” rankings.

The contrast between the forceful, high-pressure synths and Hatsune Miku’s whispery vocals is superb.

Without balancing crisp articulation and composure in the singing, you might not be able to convey the song’s cool vibe.

Listen closely to how each individual word is voiced.

I’m dead.Shiino Mirin

I’ve died — KAFU · Yuzuki Yukari
I’m dead.Shiino Mirin

Avant-garde music will captivate your ears.

This track by Vocaloid producer Mirin Shiino—who made a name with the hit “Then Let Your Ideology Die”—was released in May 2022.

Its drum’n’bass rhythm and deeply reverberant piano tone are striking, and the glitchy sounds are downright addictive.

The vocal delivery, somewhere between hip-hop and poetry reading, is another hallmark.

Figuring out how to reproduce this by human performance will be a true test of skill.

Hard Luck of the Crunchy AngelSTEAKA

A sharp, driving synth sound powers this cute yet hardcore electronic number.

It’s a track packed with STEAKA’s signature, unique worldview, released in August 2023.

Vocals are by “Decentralized Autonomous Golem Rimuru.” The addictive melody and sound design are irresistible.

Perfect for blowing off steam or when you want to hear something different.

Give this cutting-edge track a try!

Both the sound and the lyrics push a bright, fun vibe to the forefront, brimming with positive energy.

You might even find yourself grinning at how the song’s bursting feelings of love are portrayed.

LuceINE

Luce, produced in 2020 by VOCALOID producer INE—who has written songs for artists like Ado and King & Prince—is a track that unfolds with a complex sound combining electronica and rock.

Because it makes use of the uniquely inorganic quality of a VOCALOID singing voice, it’s fair to say the song is difficult to sing.

The key is to sing with a rhythmic, percussive feel in sync with the surging bassline and synth tones.

Try singing it at karaoke with IA’s clear yet somehow wistful vocals in mind.
