back number Popular Song Ranking [2026]

Emeraldback number43rank/position

back number – Emerald

It’s a digital-only single released on October 12, 2020, and it’s the theme song for the drama “Dangerous Venus.” “Emerald” emphasizes expressive power, blending delicate romantic feelings with a dark elegance.

It’s recommended for men who want to refine their control of range, emotion, and rhythm.

Another key point is how beautifully you can sing the ad-libs when the melody shifts.

The vocal range is D#3 to B4, which feels relatively restrained for back number.

It’s tough to sing unless you can switch smoothly from chest voice to falsetto, and since the key modulates upward in the last chorus, you’ll likely project better if you use more breath and sing with raw emotion.

Song of Those Who Supportback number46rank/position

Sasaeru Hitono Uta

Set to a gentle, comforting melody, this warm, heartfelt song portrays a parent’s unconditional love.

The straightforward feelings of a parent for their child are written like an everyday conversation, and the tender lyrics strike a chord.

Included on the album “blues,” released in November 2012, this piece is a gem of a ballad crafted by back number after their major-label debut.

Though it has no tie-in, it has won broad support from fans as a song that resonates deeply when you want to reflect on the bond between parent and child, think of someone dear, or remember family living far away.

Checkered one-piece dressback number47rank/position

Check No One Piece

The piece “Checkered Dress” is striking for its bittersweet lyrics that tighten the chest.

Because it interweaves major and minor keys, you might get the impression it’s hard to sing, but since there are no abrupt jumps in pitch, it’s actually easier to sing than it sounds.

The only tricky part is the beginning of the B section.

With the vowel on “o,” you have to drop the pitch twice; this approaches an advanced vocal technique known as a “fake” (ad-lib), so it does require getting used to.

The Rain and Meback number49rank/position

Ameto Bokuno Hanashi

It’s a bittersweet heartbreak song included as the 11th track on the 6th album “MAGIC,” released on March 27, 2019.

It’s a highly narrative, classic ballad that depicts the loneliness and helpless pain right after being left by a lover at a rainy intersection.

The song’s hallmark is that the verses are sung in the lower register while the chorus approaches the higher range, making it a track that really builds.

When singing, if you carry the verse’s vibe straight into the chorus, your voice likely won’t come out.

Preparing your voice is important, and keeping your eyebrows raised throughout is also a tip for staying on pitch.
