Easy-to-sing recommended songs by back number [for karaoke song selection]

sea glassback number

Sea Glass

Sea Glass, a renowned song by back number with its delicate melody, leaves a strong impression.

This piece is highly recommended for male singers with higher voices.

That’s because its vocal range is set on the higher side even among back number’s songs.

That said, it isn’t difficult: the vocal line is kept simple throughout.

While falsetto appears fairly often, the pitch movement isn’t rapid, so if you can produce falsetto and high tones without issue, you should find it easy to sing.

blinkback number

back number – Mabataki (full)

The 17th single “Mabataki,” chosen as the theme song for the film “The 8-Year Engagement,” carries a love-filled message that resonates with the movie’s story and is sure to move you.

Its friendly, shuffle-beat melody makes it easy to remember, and since the overall vocal range isn’t wide, it’s easy to sing.

However, if you’re not comfortable with the bouncy rhythm, be sure to listen closely to the karaoke track as you sing.

Although the range is narrow, the key is relatively high, so if it feels difficult, consider trying it in a key that suits your voice.

Paradeback number

Parade

Parade, a signature hit by back number, exudes an energetic vibe.

This piece features a chord progression similar to one of back number’s biggest hits, Watagashi, and unfolds with melodies and vocal lines that feel familiar to Japanese listeners.

Above all, its most singable point is undoubtedly the narrow vocal range.

Since the vocal line develops entirely within the mid-range, it doesn’t depend on the singer’s range, making it easy for anyone to sing without difficulty.

my nameback number

back number – My Name (full)

Boku no Namae o, a classic by back number released in 2016.

While it’s wrapped in a catchy melody, among the songs introduced here, this one might be a bit more challenging.

The main reason is the low falsetto that appears in the chorus.

Surprisingly, producing a piercingly high falsetto is relatively easy, but a soft, low falsetto is difficult—so those who struggle with falsetto may find this tough.

That said, it doesn’t appear often, and the notes are still within a range you can manage with chest voice, so if you boldly lower the key, the difficulty drops significantly.

To new loversback number

back number – To the New Lovers

This song, which could be called the group’s signature track, is a warm piece that weaves together the feelings of becoming a parent.

Its heartrending lyrics and melody resonate deeply.

The delicate portrayal of a parent watching over their child’s growth is moving.

Written as the theme song for a Fuji TV Monday 9 p.m.

drama, it was released digitally in July 2024.

It marks back number’s first Monday 9 p.m.

drama theme in about nine years.

It’s a recommended track when you want to reflect on parent-child relationships and familial love, or when you wish to deepen your feelings for someone important.

Wrapped in the gentle vocals, why not think of someone dear to you?

The curtain risesback number

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!

Spilling downback number

Koboreochite

Back number’s mid-period was characterized by a slightly aggressive, sharp-edged sound.

Many fans probably love the youthful melodies from that time.

A highly recommended, easy-to-sing song representing this era is Kobore Ochite.

While the band often leans pop, this track is decidedly more rock.

Its distinctly masculine melody means you shouldn’t worry too much about precise pitch when singing—go for a rougher delivery.

There’s no falsetto, so it should be comfortable even for men with a slightly raspy voice.
