Even though your heart is your own, it just won’t listen, will it… This piece is by Toa, a Vocaloid producer known for hits like “Tsugihagi Staccato,” and it was released in 2021.

It’s a gentle four-on-the-floor track where a catchy melody line intertwines with the sound of piano.

The lyrics, however, are especially relatable when you’re feeling down or pondering your own reason for being.

Rather than a straightforward cheer-up song, it feels like something that speaks on your behalf and stays by your side—an accompanying presence in musical form.
