Within the tranquil natural setting, the depiction of light emerging also evokes a relaxed atmosphere.

The song being performed in that gentle ambiance is back number’s “Heroine.” The original track is a ballad that unfolds with a calm band sound, and the soaring vocals layered over it convey a positive mood.

Supporting Actress Syndromeback number32rank/position

Jyoen Jyoyuushou

It’s a song that vividly portrays a hopeless love—one where the narrator, fully aware they’ll never be “the one,” continues a relationship in which they’re called on only when convenient.

Released as the B-side to back number’s 2012 single Aoi Haru and later included on the album blues, it depicts a protagonist who sarcastically acknowledges settling for an ambiguous relationship yet can’t stop the feelings that grow with every time they sleep together.

The fear that putting it into words would break everything keeps them swallowing the decisive confession, a detail that feels painfully real.

The groovy sound—highlighted by what Iyori Shimizu has called the standout bass line before the second chorus—is another draw, and the song became so beloved by fans that it even spawned a sequel, Supporting Actress Syndrome 2.

Daijinakoto

A warm ballad that gently depicts the misunderstandings, conflicts, and the importance of trust between lovers.

The relationship—born of strong feelings for the other person—that can bring about anxiety, hesitation, and sometimes arguments is portrayed from a down-to-earth perspective.

Released as a coupling track to the single “Hanataba” in June 2011, it was also chosen as the ending theme for NHK’s documentary program “Mirai e no Tobira.” With its calm melody line, this song is considered relatively easy to sing among back number’s tracks.

Because it invites heartfelt singing even at karaoke, it’s a perfect choice when you want to think of your partner or someone dear to you and convey your honest feelings.

Apple Pie

This is a song by back number that delicately portrays a couple’s feelings as their bittersweet memories of love slowly fade and they confront the monotony of everyday life.

Capturing the subtle distance and small pangs of loneliness between lovers with a beautiful melody, the track was included on the December 2015 album Chandelier.

As time passes, even physical affection decreases, and though they sense a crisis in a relationship that seems to be cooling, the song’s strikingly positive stance lies in finding new happiness in the ordinary—like sharing a slightly cold apple pie together.

It’s a must-listen for couples who feel they’re in a lull.

If I become a superstarback number35rank/position

Super Star Ni Nattara

This is a track that opens their major-label debut album “Superstar,” released in October 2011, and it epitomizes the band’s early intensity.

It sets a driving sound against a powerful sense of impatience to change the status quo and the fear of a relationship with someone precious coming to an end.

Through the hypothetical vow to come and get you if he ever becomes someone who shines, Iyori Shimizu’s earnest feelings as he confronts his own weakness are deeply moving.

Although not an A-side single, the song was selected for the December 2016 best-of album “Encore,” and it has continued to be cherished as an important live staple that unites the entire venue.

If you’re struggling with the frustration of wanting to change but not being able to, listening to this song will surely give you a push forward.

Endingback number36rank/position

back number – Ending (full)

A wistful ballad that gently bids farewell, like the ending of a film.

Featured on the album “blues,” this song uses a simple arrangement centered on acoustic guitar, yet it presses on the heart with the regret of not noticing the true feelings hidden behind a familiar lover’s smile.

Included on the November 2012 release “blues” and later on the best-of album “Encore” released in December 2016, the track has become a live staple and a fan favorite.

In karaoke, it enjoys enduring popularity as a song you can sing with quiet feeling, making it recommended for those who want to deliver a ballad with deep emotion.

Emeraldback number37rank/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.

Awato Hitsuji

This heartwarming song portrays a protagonist who, after repeated failures in love and everyday life, gradually learns to accept themselves as they are.

Shifting from serious lyrics to a fresh, spring-like melody and the warm tones characteristic of back number, it gently conveys an uplifting message.

Sing of springback number40rank/position

Sing of spring

Back Number’s “Turning Spring into a Song” has been beloved by many fans since their indie days.

Contrary to spring’s gentle atmosphere, the helpless feelings and lingering attachment after a farewell are penned in Iyori Shimizu’s real, down-to-earth words.

The song is included on the mini-album “Nogashita Sakana,” released in February 2009, and was later selected for their 2016 best-of album “Encore”—a number that can truly be called one of their origins.

The unadorned guitar sound, rather than being flashy, only heightens the urgency and poignancy.

In April, when meetings and partings intersect, if you listen on a night when you want to pause and sink into nostalgia, it’s a track that will quietly stay close to your heart—a song perfect for a spring night.
