nonchalant; pretending not to notice; feigning indifference4o

A stylish work that humorously portrays abandoned loneliness.

It’s a track by Vocaloid producer 4o, released in March 2023, and it participated in the Top 100 ranking of VocaColle Spring 2023.

It has a rock vibe, but the abundant use of wavering tones gives it a curious sense of weightlessness.

There’s a touch of jazz and a mature feel, too.

The playful word choices in the lyrics make it enjoyable to read on their own.

By the way, the illustration and the music video were also created by 4o.

This is a support song created by Gou Aokigi for people standing at a crossroads in life.

Released in June 2025, the piece runs about six minutes and offers a substantial listening experience.

The lyrics convey a down-to-earth sentiment toward “farewell,” and they’re moving even just to read.

The transparent band sound and Otomachi Una’s straightforward vocals gently stay close to your heart.

It’s a bittersweet Vocaloid song that sings about how feelings for someone don’t change, even as time passes and the seasons turn.

Composed by Toa, a Vocaloid producer also known for works like “Patchwork Staccato,” it was released in 2013.

The ethereal sound arrangement and Hatsune Miku’s whisper-like vocals are striking.

Perhaps because of that, the emotions woven into the lyrics seep deep into your heart.

When the autumn wind blows, you can’t help but feel a little lonely, right? This song is perfect for moments like that.

Known as a selected work for the 4th Song Contest, Project Sekai NEXT, is “Sou datta!!”.

This piece was created by the Vocaloid producer Takenoko Shounen using Hatsune Miku.

It portrays Hatsune Miku’s feelings when she suddenly forgets something important in a fleeting moment.

Its charm also lies in the slightly humorous elements woven in.

Another fun aspect is how the sound rapidly shifts—taking on an Arabian vibe in some parts and a rock-like feel in others.
