back number - Even if I someday forget

A three-piece rock band, back number, boasts immense popularity among the younger generation for their heartrending lyrics that vividly paint scenes and songs steeped in melancholy.

This track, included on their first album “Atonomatsuri” (Ato no Matsuri), is widely known among fans as a masterpiece despite never being released as a single and having no music video.

Its lyrical melody and chord progression set to a relaxed shuffle beat lend even greater poignancy to the heartbreak-themed lyrics.

It’s a hidden gem from back number, with an exceptional atmosphere that makes you feel the chill of winter’s wind.

back number – Siren (full)

While I found myself growing more at ease the more I fell in love and got to know my partner, she, in contrast, lost interest the more she got to know me.

This song focuses on the differences between men’s and women’s romantic feelings.

As my love deepened, it inversely cooled for her, leaving my feelings with nowhere to go.

Summer Wonderlandback number73rank/position

Summer Wonderland

This song was included as a B-side to the single “Old Fashion,” released in November 2018, and later featured on the album “MAGIC.” As the title suggests, it has a breezy, summery band sound, but it depicts more than just the sparkle of the season.

Shimizu Iyori deftly sings about a relationship that never quite comes to a boil and the summer heat we use as an excuse.

It’s also interesting that the track was initially crafted with a focus on performance, which ultimately led to its summery feel.

Among the tracks on the single that also includes the theme song for the TBS drama “A Love to Die For: You Who Forget Me,” this one shines with a uniquely striking presence.

It’s perfect for surrendering yourself to an energetic rhythm while savoring the slightly bittersweet aftertaste of love.

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.

A Windy Dayback number75rank/position

A Windy Day

This is a spring tearjerker that makes you empathize so deeply you could cry—the chorus is so unbearably poignant, as it recalls past memories and everyday moments with a lover, and keeps blaming oneself for wallowing in sadness.

The ending feels like the path has already been set somewhere, and Back Number’s songs never fail to capture my heart.

003back number76rank/position

003

The song “003,” a hidden gem by back number, is beloved by many fans.

While back number often paints vivid scenes, this track stands out with its abstract, slightly fantastical lyrics.

Above all, its biggest charm is the chord progression.

It closely resembles progressions long used in classic Japanese pop, making it feel familiar almost at a genetic level.

As long as you focus on the chorus’s voltage—that surge of intensity—it doesn’t actually demand a very high vocal range, so give it a try.

Included on buck number’s 17th single, “Mabataki,” released on December 20, 2017.

When you think of buck number, you might picture songs that express natural, honest emotions, but this track has a sharp, up-tempo edge.

Listening to buck number like this is really great, too.

Highly recommended.
