Karaoke Popular Song Ranking of back number [2026]

back number – Phantom Thief

This is a digital-only single by back number, released on May 24, 2021.

It was selected as the theme song for NTV’s Wednesday drama “Koi wa Deep ni.” While many recent songs feature complex rhythms and melodies, this track has a very easy-to-groove tempo, and the vocal melody is smooth and, I believe, quite easy to sing.

However, in the high notes of the chorus, the vocalist skillfully switches between chest voice and falsetto, so if you’re not confident in smoothly transitioning your vocal registers, you may want to pay a bit of attention to key settings and such.

Conversely, it’s also ideal as a practice piece for register transitions, so with that in mind, I encourage you to give it a try!

Velvet Poemback number30rank/position

Velvet Poem

Back Number’s classic song “Velvet no Uta” (“Velvet Poem”).

Released in 2022, it became well-loved as the theme song for the film Akira and Akira.

The track is crafted as a straightforward, traditional ballad.

While Back Number’s songs often feature a lot of long sustained notes, this one is relatively restrained in that regard, making it comfortable to sing even for those who struggle with breath control.

The chorus includes some slightly higher phrases, but because the melody rises in a gentle, upward-tilting manner, it should be easy to keep your pitch on target.

Sing of springback number31rank/position

Sing of spring

With their sentimental lyrics and melodies, back number captures countless hearts and never lets go.

This work is an early masterpiece included in their indie-era mini-album “Nogashita Sakana,” released in February 2009.

Spring brings gentle breezes, but it’s also a season of parting.

Feelings left unspoken and memories that resurface in quiet moments are tenderly embraced by a guitar-centered band sound.

It was also included on their 2016 best-of album “Encore,” and the fact that a music video was produced conveys that this song is especially important to them.

It’s sure to gently stay close to the hearts of those who carry words they couldn’t say.

back number – Hanabira (full)

In cherry blossom season, seeing the petals flutter down makes you feel a touch of loneliness along with the beauty, doesn’t it? Let me introduce back number’s major debut song, which captures that bittersweet spring scene.

The lyrics are striking, recalling the scenery once shared with a former lover and tightening the chest with the sense of loss that they’re no longer here.

Released in April 2011 as their first single, it was used as the ending theme for TV Tokyo’s “JAPAN COUNTDOWN.” Later included on the best-of album “Encore,” it’s a timeless classic that has been loved for years.

The contrast between joyful memories and present reality evokes a poignant ache, making this song perfect for moments when you want to sink into a pensive mood or for karaoke in March when you’re remembering someone special.

It’s a track you’ll want to sing with all your emotions.

The curtain risesback number35rank/position

back number – The Curtain Rises [Theme song for the film 'TOKYO MER: Mobile Emergency Room – Nankai Mission']

It’s the theme song for the theatrical release “TOKYO MER: Mobile Emergency Room – Nankai Mission,” hitting theaters on August 1, 2025, and it feels very much like a classic back number track.

Compared to other songs, the average vocal range is lower and the difficulty is relatively mild, making it easier to take on; however, there are lots of switches between chest voice and falsetto in the chorus and the bridge.

I think that’s the key to really delivering this song! Basically, aim to resonate in the head and sing the whole piece gently.

That way, your chest voice won’t sound forced but will come out airy and open, making transitions to falsetto smoother.

Also, falsetto uses more breath than you might think, so take in plenty of air through your mouth wherever you can breathe.

The highest note, C5, appears in the bridge; if you imagine ringing the very top of your head and push a little more firmly there, it should land beautifully!
