Songs to listen to when your heart is tired: gentle, comforting Vocaloid masterpieces

Lag TrainNEW!Inabakumo

Inabakumori 'Lagtrain' Vo. Kaai Yuki

I’m captivated by the somewhat inorganic, dry sense of speed and the layering of a childlike singing voice.

This song by the Vocaloid producer Inabakumori, whose unique musical style has earned strong support, was released in July 2020.

Depicting a sense of impatience and loneliness, as if being left behind, it features an appealing, comfortable tempo at BPM 147.

It’s also interesting that there was originally no plan to release it as a video.

In 2022, it was included on the album Weather Station, and in February 2024 it was added to Project SEKAI: Colorful Stage! feat.

Hatsune Miku and included on the CD 25-ji, Nightcord de.

SEKAI ALBUM vol.3.

Give it a listen when you’re worn out by daily life and feel like taking a moment to pause.

It’s a bittersweet yet soothing Vocaloid song that gently stays by your side when you’re feeling anxious or troubled.

The song was later included in the November 2019 album “Anticyclone.” In 2025, tie-in developments also drew attention, such as a cover version being added to “Project SEKAI: Colorful Stage! feat.

Cry and Scream, Yet Morning Comes / 4ma15 feat. Kasane Teto

Why not entrust your heart to an emotional rock sound? This track by 4ma15 was released in April 2017.

Originally put out under the then-name 12uck, it’s one of their signature songs and is also included on albums such as Wandering Through Sleepless Nights.

The piece portrays the fragility of the individual that becomes stark under the glare of daylight, and the feeling of being saved by the darkness of night, all carried by Kasane Teto’s raw, visceral vocals.

Confronting head-on the emotions worn down by society’s pressure to conform, this work gently lifts them up.

On nights when you’re overwhelmed by loneliness and don’t know what to do, it will surely stay close to your heart.

Sleeping Beauty (feat. IA)NEW!Guiano

Guiano – Sleeping Beauty (feat. IA)

A bittersweet yet beautiful Vocaloid song that gently stays close to the pain sleeping deep in your heart.

It’s a track by Guiano, a beloved Vocaloid producer known for a unique musicality that defies genre, released in May 2018.

The delicate, floating feel of the electronic sounds, the wistful chord progression, and IA’s crystal-clear vocal lines intertwine exquisitely, quietly stirring the listener’s heart.

The lyrics, depicting loss and feelings that can’t be conveyed, sink in deeply on nights when you feel crushed by your own powerlessness.

Also included on the album “Love & Music,” this piece is sure to become a song that stays beside you—someone who, while carrying loneliness and pent-up feelings, prays for another’s recovery.

Avanna Like a human beingNEW!YASU

Avanna Like a human being (remastered)

This song by Yasu had a remastered version released on SoundCloud in April 2021.

It’s a sophisticated, urban pop track that makes full use of the smooth singing voice of the English speech-synthesis software AVANNA.

With a pleasant soundscape that evokes jazz and lounge vibes, it’s the kind of music that will leave you spellbound.

Since September 2019, it has also been used as the ending theme for the online show “Umeha Radio,” and it has remained beloved for a long time.

The worldview of its English lyrics—precisely because they don’t fully reach the human heart—resonates all the more earnestly, gently lightening a hazy mood.

It’s the perfect song for quiet nights or those moments when you’re a bit tired and want to bask in a tender afterglow.

Chocolate Milk / Apvella feat. Hatsune Miku

If you’re in the mood for a chill sound, definitely give this track a listen.

It’s a work by Apuera, a Vocaloid producer who’s also active under the name Aqu3ra, released in September 2019.

Hatsune Miku’s fragile vocals pair perfectly with the crisp, catchy beat, making it incredibly easy on the ears—the sound feels like it seeps deep into your heart.

That said, the lyrics are bittersweet, expressing feelings for a precious person who’s no longer here.

JOYSOUND announced it would be available for karaoke starting in February 2020, and it’s since become well-loved by many.

Try listening to it at night when you want to spend some quiet time alone.

August 32 / Kou feat. Hatsune Miku

It’s a self-remake of a song originally unveiled in August 2013 with Kagamine Rin and Len on vocals, now reinterpreted with Hatsune Miku’s voice.

The dramatic rock sound blends beautifully with a lyrical melody that evokes the humidity of late summer.

Its highly narrative world—depicting thoughts of lost time and someone long forgotten—seeps deeply into the listener’s heart.

Give it a listen when you feel like pausing amid daily life, or on nights when you want to dwell on memories of the past.
