We’ll introduce everything from staple tracks to the latest releases, as well as songs that showcase unique ideas.

Many of these pieces carry a touch of melancholy, so why not listen with an ear for the emotional side of Vocaloid vocals?

“Coin Locker Baby” is a shocking number that also serves as the title track of MARETU’s first full album.

It’s a song that weaves heavy themes—escapism, despair, inner conflict—into poetic expression.

Praised as a fresh take on Vocalo-rock, it pairs a subject so heavy it’s no exaggeration to call it “weighty” with unexpectedly bright turns, which makes it cut even deeper.

Perfect for when you want to confront the darker side of humanity.

Koukatsu by MARETU, released on March 16, 2018.

It’s said to be astonishingly addictive—once you hear it, you’ll want to listen again and again.

The dark tone and strongly message-driven lyrics are quintessentially MARETU.

The more you ponder the meaning behind the message packed into this almost aggressive-sounding track, the more you’ll be drawn into its world.

The suddenly inserted cute voice in the interlude gives off an eerie impression, and the rap is cool as well.

Highly recommended if you’re looking for a song with serious addictiveness.

A Vocaloid track that’s light yet heartrending, catchy yet tightens your chest.

It was an entry in the VOCALOID Collection 2023 Summer TOP 100 ranking.

The song has a vibe like you’re racing through the night, and Miku’s innocent voice fits it perfectly.

The lyrics’ worldview is a bit lonely, but there’s a curious warmth to the atmosphere as well—very much the hallmark of MIMI’s music.

The lyrics evoke the image of a protagonist who, though hurt by heartless words from those around them, still strives to look forward.

Please sing it with all your heart.

It’s a polished electric number that can’t be summed up by the word “cool” alone.

Born from ESHIKARA, a project that creates Vocaloid songs from illustrations, this piece is a track by Vocaloid producer Mikade, released in April 2023, and was created based on an illustration by Yoda.

The powerful lyrics—“Don’t make excuses, move forward as yourself”—are truly stirring.

Its stylish sonic design intertwines with that message to create a one-of-a-kind world.

The Japanese-style rock melody and the fantastical world inspired by red spider lilies leave a strong impression.

Released by Nem in June 2013, this piece blends cool guitar and bass sounds to create an emotionally rich finish.

The lyrics portray the bond and affection between the two characters who appear in the song, as well as their feelings about parting.

What happens to them in the very end…? Please find out for yourself.

The vocal range should also be comfortable for those with lower voices!

This is one of the songs that helped popularize the name “Hatsune Miku.” It’s a work by OSTER project, a Vocaloid producer who’s also active in the mainstream scene, released in 2007.

As the title suggests, the lyrics convey feelings from Hatsune Miku’s perspective.

In the very early days of the Vocaloid scene, many songs focused on expressing a Vocaloid’s thoughts, and among them, “Koisuru VOC@LOID” drew particular attention.

If you’re a woman looking to get into Vocaloid music, this could be a great place to start.
