Opera! Space opera!Nayutan Alien

A pop and catchy song set in space.
Written specifically for Project Sekai: Colorful Stage! in May 2024, it quickly gained popularity.
With NayutalieN’s signature mixture-rock sound, it invites listeners on a grand adventure.
The lyrics depict journeys aboard a spaceship and bonds with distant beings, revealing something new with every listen.
It’s sure to hype up karaoke sessions and live streams, so grab some friends and sing it loud and lively!
The princess sleeps to electronic sounds.Bee

As the title suggests, this is a track packed to the brim with electronic sounds.
But it’s not just about electronics—the melody, woven from many different tones, dresses the song up like a little stage play.
Its cute yet distinctive world will surely bring a smile to listeners’ faces.
One thing to note, however, is that the lyrics depict what happens after another song.
Please listen to it together with that track, “In the Rainy Town, Balloons Dance with the Devil,” and see what impressions you come away with.
Ghosts Trying to Be FunnyPinocchioP

For anyone thinking, “This year, I want to try a ghost cosplay!”, the perfect Vocaloid song is “Obake no Uke Nerai” (“A Ghost’s Bid for Laughs”).
Created in 2018 by PinocchioP, a Vocaloid producer known for tracks with a distinctive worldview, it features striking lyrics told from a ghost’s perspective, fretting over how to scare people.
Alongside Hatsune Miku’s mechanical vocals, it paints a resolve to live true to oneself.
It’s fun even just to strike ghostly poses to the catchy, danceable chorus beat! Give this dance number a listen and let it elevate your Halloween across cosplay, singing, dancing, and more.
SimilarlyVocaloid Mutual Aid Association

It’s a heartwarming song with a beautiful melody and warm lyrics, and the nostalgic vibe is soothing as well.
The harmonies throughout and the tuning of Hatsune Miku and KAITO in the final chorus can only be described as outstanding.
Also, the creators’ group, the Vocaloid Mutual Aid Society, ended their activities in 2011 and has since become less well-known.
It’s truly a hidden gem.
OrdinaryPolis Piccadilly

When we think of autumn, it’s a season where everyday life continues without long vacations or major events like in other seasons.
A song that perfectly fits such an autumn is Police Piccadilly’s number “Ordinary.” The title of this track, when translated into Japanese, means “normal” or “everyday,” making it a perfect match for the autumn vibe.
Yet it’s also emotional, giving the song a strangely moving, almost mysterious feel.

Oonawa Children's SongMushipi

A song by Mushipi themed around double Dutch.
Released in June 2024, this work features lyrics strikingly told from a child’s perspective.
Hatsune Miku’s transparent vocals portray the complex emotions of the protagonist who can’t manage to jump in while other children are skipping rope.
In contrast to the bright melody, feelings of loneliness and inner conflict resonate deeply.
The charm lies in the contrast between the pop rhythm and the heartrending lyrics, making it a track that leaves a lasting impression.
It’s recommended for times when you want to reflect on childhood memories or sort through hidden emotions.
A highly addictive piece that lets you fully savor Mushipi’s unique worldview.
Please dance.Yurii Canon

A signature song by Yuri Cannon, a renowned Vocaloid producer who embodies a fusion of traditional Japanese style and Vocaloid.
It’s high-tempo and high-pitched, making it a challenging choice for first-time singers, but it looks incredibly cool when mastered.
If you imagine the iconic Vocaloid track Senbonzakura, you’ll get a similar vibe.
Highly recommended for those who are good at fast-paced lyrics.
By the way, Yuri Cannon also expresses pure Japanese-style rock in songs like “Suicide Parade” and “If I Could Become Someone’s Heart.”
