[Male and Female] A Compilation of Vocaloid Duet Songs [Also Great for Karaoke]

rayBUMP OF CHICKEN feat. HATSUNE MIKU

BUMP OF CHICKEN feat. HATSUNE MIKU「ray」

Released in 2014, “ray” exquisitely matches the beautifully delicate vocals of Hatsune Miku with the sound crafted by BUMP OF CHICKEN to create a unified world.

Its catchy, pop-leaning melody and lyrics that remind us of the importance of facing forward, even when everyday life is tough, are major draws of the song.

Another distinctive feature is how the vocal parts alternate between BUMP OF CHICKEN’s vocalist, Fujiwara, and Hatsune Miku’s main melody.

The way one takes the lead while the other harmonizes unveiled new possibilities for the fusion of Vocaloid and band music.

I Wanted to Be Someone’s Hero / feat. IA & Yukari Yuzuki

This is a message song that teaches the importance of believing in yourself.

It was released in 2018, with lyrics and music by Tota Kasamura.

It’s a duet by IA and Yuzuki Yukari, but it also has the feel of a choral piece, so when you sing it at karaoke, feel free to sing it together with everyone.

The heartrending melody line and the sound of the piano are truly moving.

It’s a song you’ll want to listen to during graduation season.

Entanglement / Rupo Ichinose feat. Kagamine Rin & Len NT

This is a refreshing electronic track released in October 2025 to commemorate the launch of the voice library “Kagamine Rin/Len NT.” Created by Rupo Ichinose, the piece explores the theme of a “tangle” that links the past, present, and future.

Using digital motifs like zeros and ones and programming, it portrays human connections and the workings of the heart.

The shimmering synthesizers and clear vocals weave a soundscape that truly embodies the fusion of new technology and emotional expression.

When you feel ready to step toward the future, be sure to give it a listen!

[Kagamine Rin/Len] Gemini [Original]

The twin duo, Rin and Len, are singing.

“Gemini” means the constellation of twins.

Surely these two trust each other.

It’s a song with a very gentle and calm atmosphere that conveys that feeling.

Also, don’t miss Len’s rap in the latter half.

[Kagamine Len · Hatsune Miku ┗|∵|┓] Crybaby Boyfriend [Original PV]

It’s likely to resonate especially with junior high and high school students.

This is a heartbreak song that portrays a painful farewell and the end of love.

It’s the second work by the creator unit HoneyWorks, released in 2010.

While it’s a rock ballad that tightens your chest, the lyrics also carry a message that can help you look forward.

Try singing it when you want to have a good cry.

Red Purge!!!P.I.N.A.

Kagamine Rin/Len - Red Purge!!! (Original MV)

How about a sophisticated Vocaloid track with a crisp, lingering vocal tone? It’s a song by the Vocaloid producer P.I.N.A., also known for works like “The Rat Died,” released in 2014.

A four-on-the-floor number with a somewhat dreamy atmosphere and highly addictive appeal.

It strikes a balance where coolness and intensity can be felt at the same time.

The tuning that lifts the pitch at the ends of phrases is also striking.

You’ll find yourself drawn into the philosophical lyrics.

The melody is quite challenging, so it’ll take practice.

Heaven and HellHitoshizuku-P × Yama△

[Kagamine Rin/Len] Heaven and Hell [Original]

The hard rock-style sound arrangement is insanely cool! It’s a track by Hitoshizuku and Yama△, who have created many popular works like “Bad ∞ End ∞ Night,” and it was released in 2013.

The intense yet catchy, easy-to-groove-to vibe is totally addictive.

The humorous back-and-forth between Rin and Len is another highlight.

The playful lyrics—“Choose heaven or hell!”—also leave an impression.

Highly recommended when you want to hype up a karaoke session.

It might be perfect as the first song to sing.
