The smartphone game “Project SEKAI COLORFUL STAGE! feat.

Hatsune Miku”—if you’re reading this article, there’s a good chance you’re already playing it.

For those new to it, it’s a rhythm game featuring famous Vocaloid tracks, brand-new songs by Vocaloid producers, and pieces selected through public submissions.

It’s especially popular among teens and people in their twenties.

In this article, we’ll introduce songs from ‘Proseka’ that are relatively easy to sing and great for karaoke! We’ve mainly picked each unit’s signature tracks.

Be sure to try singing them with your Proseka friends!

[Karaoke] A roundup of easy-to-sing Project Sekai songs (1–10)

An addictive track that dominates the stage with a kingly swagger.

This mega-hit number, written and composed by the hugely popular Vocaloid producer Kanaria, is covered by Tsukasa Tenma and Rui Kamishiro.

It delivers a somewhat defiant, theatrical, and thrilling worldview.

Added to the game in May 2021, it also featured in a collaboration with Ensemble Stars!! in February 2025, drawing major attention.

We recommend singing it as if you’re the song’s protagonist.

“Passion at 25 O’Clock” moves the heart with its beautiful vocals and stirring melody.

Crafted by Kanzaki Iori, whose music is celebrated for its nuanced emotional expression, the song delicately portrays the wavering feelings of youth and the journey of personal growth.

In particular, its message—focusing on unforgettable memories, the weight of passing time, and evolving relationships—resonates deeply with listeners.

Since the melody is on the slower side, try to articulate each word with care.

The rapid-fire lyrics delivered over a brisk BPM of 172 are phenomenal—almost like chanting a spell.

The feeling of satisfaction when you make it through without tripping over the words is unbeatable.

This is a crystal-clear piece whose delicate piano tones seep into the heart.

“Milk Crown on Sonechka,” sung by MORE MORE JUMP! and Hatsune Miku, is a song originally written and composed by Vocaloid producer YZYx (Yuji).

Its lyrics, inspired by a “coronation ceremony,” express the frustration of lacking self-confidence and the desire to accept oneself nonetheless.

With a mid-tempo of around BPM 127, it should be easy to follow the melody.

Written and composed by EasyPop, this song’s lyrics express a gentle, forward-looking wish to lighten your downcast heart through the power of music.

Beloved since its release in November 2010, it’s a classic; in Project SEKAI you can enjoy a four-vocal version by Hatsune Miku, Kagamine Rin, Megurine Luka, and MEIKO.

With its straightforward melody and easy-to-catch rhythm, it’s perfect as the first song at karaoke!

A fiery track born from the collaboration between Vivid BAD SQUAD and Hatsune Miku, “Realize.” Crafted by Shiina Magentite (Hiiragi Magnetite), this song portrays a journey of challenge and growth.

The lyrics genuinely give you courage and fire you up.

It’s fast-paced with powerful rap, yet composed with singability in mind, so it’s sure to shine at karaoke.

If you’re aiming for a dynamic performance, definitely choose “Realize.”

Pulse of the MeteorLeo/need × MEIKO

An emotional rock number that shakes your heart with its dynamic sound.

Leo/need’s “Meteor Pulse” is a newly written track by Vocaloid producer *Luna, known for hits like “8.32.” The arrangement blends clarity and heat, making it impossible not to keep turning up the volume.

The powerful vocals also fit the song’s style perfectly.

When singing, especially in the chorus, try aligning the vocal melody closely with the song’s rhythm.

Doing so will help you express the dynamic contrasts of “Meteor Pulse” even better.
