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

back number – With Love from a Certain Future [MOS Burger “Eating HAPPY” Commercial Song]

This is a newly written song for Mos Burger’s new brand commercial “Eating HAPPY,” airing from June 20, 2025.

When it comes to actually singing this song, the range is very wide! The overall range spans A#2 to C#5, with the verses (A and B sections) centered on lower notes, and the chorus shoots way up! The jumps are quite extreme, but the melody is clearly divided by section, so I think it’s relatively easy to practice.

If the high notes in the chorus feel “too high” in chest voice, it’s totally fine to approach them from falsetto! When I teach high notes, I sometimes have students master falsetto first and then transition to chest voice! Once you get used to it, chest voice will definitely become easier to produce, so sing with confidence.

Lifeback number

Life

back number’s classic “Life.” The song features a chord progression that really showcases their signature style, yet it carries a slightly punk rock vibe.

Unlike many back number tracks that call for surprisingly delicate vocals, this one works even if you sing it pretty roughly, so it’s a good choice for those who struggle to produce a clean tone.

There’s a falsetto at the end of the chorus, but since it’s a low falsetto, if you want to emphasize the roughness, you could even try singing that part in chest voice instead.

apple pieback number

Apple Pie

Apple Pie, included on their 11th single Heroine.

It’s a refreshing, guitar-riff-driven number said to have been arranged from a song that had existed for five years before being released as a B-side.

The cute, familiar melody doesn’t span a wide vocal range, making it perfect for those who want to try singing a back number song but aren’t very confident at karaoke.

However, be careful not to go off pitch, as there are many falsetto parts throughout.

Song of Those Who Supportback number

Sasaeru Hitono Uta

The song “Sasaeru Hito no Uta,” included on the second major album “blues.” Reading the lyrics, written from the perspective of someone devotedly supporting a loved one, may bring to mind the person who plays that role in your own life.

Although the overall key is high, the vocal range isn’t wide, so even if the original key feels difficult, it becomes easy to sing by adjusting it to your own key.

With a friendly, gentle melody that colors the message, it may not be an A-side single, but it’s a hidden gem you’ll definitely want to add to your karaoke repertoire.

Express train to home for self-reflectionback number

Hansei Kyuukou Jitakuiki

back number’s heartbreak song “Reflection Line Express Bound for Home” overflows with a sense of speed.

It’s a breakup song that brilliantly captures their signature lingering attachment, wrapped in a sharp, early-2010s alternative rock melody.

The guitar riff has a slightly Asian Kung-Fu Generation-like feel.

Among back number’s catalog, this piece is particularly easy to sing.

With its generally narrow range and straightforward vocal line, it’s very singable; however, because it features a lot of long sustained notes, it’s recommended for people who are confident in their breath control but not necessarily in their overall vocal technique.

Hold on a second with that dress.back number

Hold on a second with that dress.

“Wait a Second, That Dress,” included on the first album At no Matsuri (Aftermath).

The lyrics, which depict the complexities of a man’s heart so vividly that you can imagine the story from the title alone, are likely to resonate with many men.

The upbeat rhythm feels comfortable for karaoke and the vocal range isn’t wide, but be careful not to fall behind since the melody moves a bit quickly.

It’s a pop tune that blends bittersweet yet somewhat comical lyrics with a friendly melody, and will likely be a hit—especially at karaoke sessions with an all-male crowd.

Supporting Actress Syndrome 2back number

Jyoen Jyoyuushou 2

“Supporting Actress Syndrome 2,” included as the B-side of back number’s 14th single and signature song “Christmas Song,” is a sequel to “Supporting Actress Syndrome,” the B-side of their 7th single “Aoi Haru.” Even if you haven’t experienced it yourself, the storyline lyrics have a heart-wrenching poignancy that tightens your chest.

The catchy melody, set against an ensemble that creates an unsettling undertone, is addictive and sticks in your ears, making it easy to remember as a karaoke repertoire choice.

While the overall vocal range is narrow, there are many melodic leaps, so be careful not to miss the pitches.
