[Challenge] A Compilation of Vocaloid Songs That Are Hard to Sing (21–30)
Goblin shark?Hiiragi Kirai

“Loveca?” is known as one of the signature songs by Hiiragi Kirai, a Vocaloid producer with numerous hits.
The track drew attention alongside a cover version by Ado.
It unfolds a hefty electro sound laid over the breezy rhythm characteristic of swing jazz.
Mastering Flower’s vocals, which display a wide range of expressions, can be challenging.
In the chorus, where rhyme is used frequently, the key is to deliver a rhythmic performance without running out of breath.
Why not try tackling a Vocaloid song that takes a cynical look at themes like “love” and “lies”?
lifegcmstyle

You can’t predict how it will unfold—in fact, it’s a piece that crams a variety of musical styles into a single track.
It’s a song by gcmstyle, also known as Anmeltz-P, released in 2022.
It drew attention when it was selected for the ultra-difficult song contest “Project Sekai ULTIMATE.” It kicks off with a fiery mixture rock vibe, then shifts into a bright, cheerful A-melody.
From there it jumps to hip-hop, blisteringly fast electro with a super high-speed melody, EDM with English lyrics, metal, a piano ballad—the style keeps changing at a dizzying pace.
It’s a short track, but the sense of satisfaction you feel after listening is absolutely off the charts!
spring stormjhon

Jhon is a Vocaloid producer who also provides songs to artists under his solo project TOOBOE.
His 2019 release “Shunran” is a poignant Vocaloid track themed around springtime farewells.
It features a driving electronica sound paired with Hatsune Miku’s rhythmic vocals.
Because the lyrics unfold rapidly, the breathing spots can be tricky.
The key is to deliver crisp, articulate singing that follows the melodic progression.
It’s a Vocaloid song with a bittersweet yet resonant melody—be sure to give it a try.
TetrisHiiragi Magunetaito

Right now, the most talked-about Vocaloid track is “Tetris.” It’s a new song by Hiiragi Magnetite, characterized by a flashy sound that carries a touch of denpa-style essence.
While this piece doesn’t necessarily feature ultra-high phrases, it’s packed with high lines throughout, and the pitch leaps are extremely sharp, giving it an overwhelming level of difficulty.
With few break points, it also demands strong lung capacity—another challenging aspect.
Be sure to add it to your repertoire.
danceAdo

It was selected as the theme song for NHK’s music program “Yakou Ongaku VocaloP 5min.” I hear the show features a different Vocaloid producer each time and introduces how Vocaloid music is made.
Among those songs, many people probably think, “I want to sing that!” when it’s a track sung not by a synthesized voice but by Ado.
I like ‘Odo’ too and used to sing it a lot, but when I thought, “Let’s sing it again after a while!” and tried it at karaoke the other day, the melody had completely slipped my mind and I couldn’t sing it at all…
It really drove home how, if you don’t listen regularly, you forget such a complex melody.
I get the impression it has dramatic pitch jumps and lots of melodic figures.
Still, the belted parts in the chorus are truly cool, and it feels great to sing—highly recommended!
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?
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!
