To Those Who Know the Blue of the Skyaimyon78rank/position

Aimyon – A Person Who Knows the Blue of the Sky [OFFICIAL MUSIC VIDEO]

This is Aimyon’s ninth major-label single, released in October 2019.

It serves as the theme song for the animated film of the same name, “Her Blue Sky.” Over a medium-tempo, symphonic backing track, Aimyon’s slightly husky vocals sound especially captivating.

In the latter half, the melody develops in ways that are relatively complex compared to other songs featured in this article, so the difficulty level for singing may be somewhat high.

That said, if you study the song thoroughly beforehand, even those who aren’t confident singers should find it far from impossible—so definitely give it a try.

Yorushika – Ghost in a Flower (OFFICIAL VIDEO)

For those who struggle to decide what to sing at karaoke, I recommend “Hana ni Bourei” (“Ghost in a Flower”).

It was released in 2020 by Yorushika, a rock band immensely popular especially among Gen Z.

Many listeners will relate to its poetic lyrics that capture a page of “youth.” The technical guitar riffs etched into the wistful band sound are striking, and suis’s clear vocals soothingly narrate a bittersweet summer story.

When singing it, the key is to relax and deliver it as if you’re speaking to someone.

Since the song unfolds within a steady vocal range, karaoke beginners should definitely give it a try.
