Supporting Actress Syndromeback number31rank/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.

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 number33rank/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.
