[Challenge] A Compilation of Vocaloid Songs That Are Hard to Sing (21–30)
Panopticonr-906
Panopticon resonates with a sound that matches VOCALOID’s mechanical aesthetic.
Created in 2019 by Vocaloid producer r-906, who specializes in electronica-based music, it features a driving sound propelled by a surging bassline intertwined with dynamic drums.
The track leverages mechanical vocalization—such as counting letters in romanization one by one—making it challenging to sing.
The key is to focus on staying in the groove and maintain a steady level of intensity.
Why not try singing this one-of-a-kind Vocaloid track that blends human emotion with the uniquely mechanical sound only VOCALOID can offer?
Sequelae, memo, time bomb.Satsuki
Vocaloid producer Satsuki’s work “Aftereffects, Memoir, Time Bomb” is a piece that carefully portrays the darkness of the heart.
The first half depicts a gloomy atmosphere over a near-futuristic sound.
From the second half, it modulates into an intense sound, building to a climax that features ultra-high-speed singing.
Try listening while pondering the meaning behind the title and the division of vocals between Hatsune Miku and Kaai Yuki.
By the way, the latter half is quite fast-paced, so I recommend starting with the music video that displays the lyrics.

CH4NGEGiga
CH4NGE resounds with a sound that evokes a glamorous clubhouse dance floor.
Created in 2021 by Giga, a Vocaloid producer with numerous hit songs, it features Hatsune Miku’s sultry, cool vocals riding over a heavy electronica sound—truly striking.
While the song unfolds through various sections, you’ll sing it well if you keep the four-on-the-floor beat in mind.
The lyrics feature plenty of rhymes, so it’s also helpful to memorize and practice the repeated phrases.
Try delivering a performance that balances passion with cool composure for your audience.
Six Trillion Years and an Overnight Storykemu
Released in December 2012, this song is a classic, notoriously difficult Vocaloid track! It has a Japanese-style vibe with a very relaxed intro, but the tempo suddenly speeds up and the lyrics become extremely dense.
You’ll need to be mindful of stamina, lung capacity, and quickness, but it’s highly recommended if you love fast songs! The key to singing the rapid-fire sections is not to try to articulate every single consonant, but to clearly pronounce the vowel sounds that carry the accents.
That will help you lock into the rhythm and sing more lightly.
With fast-tempo songs, above all, you have to memorize the lyrics; otherwise, when you sing it at karaoke, you’ll end up just chasing the words and sounding vague.
I recommend first being able to hum the melody, then adding the lyrics afterward!
PlayPikon
“Playback,” produced in 2021 by Vocaloid producer Picon, who is known for songs with a unique worldview, depicts scenes of recalling days spent with a loved one and sings of a reality that feels like a dream.
Within its soundscape tinged with traditional Japanese ambience, the heartrending melodic lines are sure to bring tears.
Though the song unfolds at a slow tempo, sustaining a gentle, high register throughout is challenging.
It’s a grand ballad featuring Hatsune Miku’s crystalline vocals that resonate with feelings so moving they could draw tears.
Why not take on this song, imbued with beautiful yet fragile emotions?
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.Shino 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.
