【Ka Fu】Cute Girlfriend【syudou】

Although already a Vocaloid producer with many hit songs, syudou became widely known thanks to the massive success of “Usseewa,” which he provided to the female singer Ado.

This track features breathy, lifelike vocal tuning and lyrics that verbalize unstable emotions, creating a strong impact.

With its high starting key, intricate melodic turns, and rapid phrases, it exemplifies the difficulty of modern, evolved Vocaloid numbers.

Precisely because of that, it’s a song I’d love for you to try in karaoke—though it’s a pretty high-difficulty piece.

LaviSorry

Lavie / Surii feat. Kagamine Len

Vocaloid producer Surii, who began making music inspired by the TV anime K-On! and has multiple Hall-of-Fame tracks, released his 20th song “Luv,” which was chosen as the theme song for a character in the mobile game #Compass: Combat Providence Analysis System.

It’s challenging not only because it maintains high notes throughout, but also due to its intricate melody; however, once you can sing it, karaoke becomes even more enjoyable.

With over 10 million views on YouTube, it’s a number that many people are likely to know.

Tinplate Dance

Among Vocaloid tracks where not only the music but also the MV is considered part of the appeal, producer Hinata Denko is known for competing with just the music alone—using only a single thumbnail image.

This song, the first of their works to hit a million plays, features a thrilling guitar riff and relentless melodies that really get you fired up.

With rapid-fire delivery, frequent melodic leaps, and even passages in a high key, it compresses the hallmarks and challenges of Vocaloid music into a high-difficulty number.

But that’s exactly why, if you can nail it at karaoke, you’re guaranteed to be a hero.

Emotional Deceivero-aru

Emotional Deceive

A Vocaloid song by Ro-aru, released in April 2022.

It’s a piece marked by an energetic tempo and a wonderfully satisfying chorus.

You can feel the protagonist’s pain as they’re trapped in jealousy and inferiority born from comparisons with others, caught in a negative spiral—it’s hard not to empathize.

At the same time, the song also carries a strong will to overcome those struggles.

When you face hardships or setbacks in life, it might be good to sing this song while recalling the message it conveys.

collapse; fainting spell (colloquial/slang)Iyowa

Kyu-kurarin / Iyowa feat. KAFU

A track by Vocaloid producer Iyowa, who made their debut in their second year of high school and took their name from having a weak stomach.

The slightly unstable yet cute intro, the catchy pop melody that sticks in your ears, and the arrangement that seems to blend both drive and weightlessness make a strong impression throughout the song.

With its fast tempo, high key, and tricky elements like sudden beat changes mid-song, you might find it difficult to sing perfectly at karaoke.

However, precisely because of that, it feels great if you can make it through—so try singing it with the intention of pushing your limits.

An intro marked by the softly resonant piano notes—“tan… tan…”—leaves a striking impression.

From there, you can imagine a story unfolding in a cold, unfamiliar world that’s about to begin.

The uninterrupted flow of tones and the satisfying clarity of the vocals laid over them create a comfort that’s simply irresistible.

As the creator described it as a “Frozen Nonsense Theater,” the song sometimes proceeds exactly as we expect, and at other times boldly subverts those expectations, offering surprise and delight.

It’s a challenging song to sing, but it’s one that makes you want to try and present your own expression.

Absolutely hostile, super hate ya!Medmia

Absolute-Enemies, Super-Detest, Yaaah! – Miku and KAFU

“Absolute Adversary Mega-Kirai-ya,” a track released in April 2022 by Medomia, a Vocaloid producer born in 2000.

It’s a cool song with a driving drum beat and a catchy chorus melody that sticks in your head after just one listen.

When you try to sing it, you’ll probably find the beginning fairly easy.

However, once the chorus hits, the required vocal range jumps up significantly.

The highest note in the song is hi G (G5), which appears near the end.

It happens in the final sprint, after a key change that raises the key by one more step for the last chorus.

Give it your best shot using falsetto and mixed voice!
