Karaoke Popular Song Ranking of back number [2026]

Emeraldback number29rank/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.

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.

back number – No Matter What, No Matter What [Lyric Video] (NHK Winter Sports Theme Song)

The rock band back number has long resonated with many listeners through their poignant lyrics and melodies.

Released via streaming in December 2025, this track was written as the theme song for NHK Winter Sports.

It also helped energize broadcasts related to the 2026 Milan-Cortina Winter Olympics.

The lyrics, which depict unwavering persistence and the determination to keep challenging oneself, really strike a chord.

They brim with kindness that seems to affirm not just the results, but also the struggles and gritty emotions along the way.

It’s a song we want not only athletes, but everyone striving toward a goal to hear.

It will rekindle the fire within you!

Sing of springback number32rank/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 – Yellow

This is a classic ballad written as the theme song for ABEMA’s romance show “Don’t Be Fooled by the Wolf and the Rainbow,” portraying the bittersweet feelings of unrequited love through metaphors like a “yellow traffic light.” The music video, directed by Yuki Yamato, has become a talking point as a “music video that deepens understanding even without dialogue.” The song’s overall vocal range is D3 to B4, which is somewhat wide and requires skillful use of both chest voice and falsetto, but I think it’s a piece that can be carried more by expressiveness than by pitch accuracy.

If you sing while infusing the lyrics with your feelings and emotions, it will become a thoroughly good performance.

back number – fish (full)

A bittersweet yet beautiful “Scab Song” that portrays a woman’s wavering heart in the face of parting.

Cherished since their indie days, this special track was completed under the production of Masanori Shimada, blending delicate lyrics with a grand sound.

The overall vocal range is a relatively calm F3–A#4, and the song itself has a gentle mood; since it surges all at once in the chorus, the key is to really project your voice.

There are many sustained phrase endings, so focusing on diaphragmatic breathing and taking deep breaths should make it easier to sing.

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.
