This song portrays that situation.
The realistic and very heartrending lyrics strike a chord with listeners.
003back number

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.
HAPPY BIRTHDAYback number

If you can sing this one too, it’s truly cool—a moving song that can bring listeners to tears.
The opening lyrics and the quiet, acoustic, singer-songwriter feel make for a captivating introduction.
The way it steadily builds links with the drama of the lyrics, and if you practice a lot and pour your heart into the chorus, you just might capture your listeners’ hearts—perhaps that’s the kind of song this is.
Sisterback number

The lyrics are irresistibly uplifting and positive.
It’s the kind of motivational song you’ll want to share with someone who’s about to take on a challenge, someone you want to cheer on and give a gentle push forward.
Among the many songs by back number, this is a beloved masterpiece of mine.
Song of Velvetback number

Known for their poignant yet powerful ballads, back number has a solid reputation.
Their song “Velvet no Uta” (“Song of Velvet”) sings about the hardships of life and the hope that shines through them.
It’s also been making waves as the theme song for the film Akira and Akira.
Among back number’s catalog, this track is said to have particularly deep lyrics, and analyzing it has become a trend on social media.
Give it a listen and see what message you take away from it yourself.
Sympathyback number

A laid-back masterpiece from Nigasareta Sakana! Personally, I think the chorus melody is one of the most beautiful among back number’s songs.
It uses a lot of falsetto, which deepens the sense of wistfulness.
If someone sang it at karaoke, plenty of girls might find their hearts skipping a beat.
