Number_i's popular song ranking. A compilation of masterpiece tracks that transcend genres.

Rain or ShineNumber_i22rank/position

Rain or Shine

This is the track I want you to sink into on a quiet night alone.

It was included on “GOAT,” the single released in March 2024 by Number_i, a group drawing attention in the music scene with their unique performances.

A breeze-like, silky melody blends with the members’ relaxed vocals to gently unwind the listener’s heart.

The lyrics softly say there’s no need to put on a brave face, offering a comforting sense of being by your side no matter the weather.

It’s a hip-hop tune that captures their chill side, distinctly different from flashy dance numbers.

On sleepless nights or rainy days, let this gentle groove that fits into everyday life wash over you.

SQUARE_ONENumber_i23rank/position

SQUARE_ONE

A track from the album “No.O -ring-,” which also drew attention for being produced by PUNPEE.

The skillful rap laid over a low-center-of-gravity beat and the expansive vocals in the chorus create a pleasing contrast.

With lyrics themed around “starting over” that affirm a fresh beginning, it overlaps with Number_i’s image of forging a new path and gently pushes listeners forward.

Released digitally in May 2024, it’s also fresh in our memories for the passionate performance at THE MUSIC DAY 2024 in July of the same year.

Because it’s imbued with a resolve to aim for one’s own summit rather than comparing oneself to others, it’s a sure-fire track to give you positive energy when you need courage to change your current situation.

Bearing a single alphabet letter—symbolic of the group’s name—as its title, this work wraps the small joys of everyday life in a grand, gospel-inspired sound.

Produced by member Sho Hirano, it expresses his own aesthetic and the kindness at the core of the group.

Included on the mini-album “No.O -ring-,” released in May 2024, the song radiates a warm presence that stays close to the listener’s heart amid a collection of more aggressive tracks.

In 2025, it was also selected as the theme for KOSÉ’s Sekkisei commercial, with its clear, translucent worldview becoming a hot topic.

It’s a track you’ll want to hear when you’d rather savor “a handful of happiness” than chase flashy success—when you want to return to an authentic, down-to-earth state of mind.

iLY

The KOSE SEKKISEI commercial “i Bright.

Facing forward, with this skin.”, which features close-ups of the three members of Number_i, is striking for its transparent, lucid visuals.

The lighting, which seems to capture reflections on a water surface, is especially memorable, and combined with the white background, it creates a very fresh atmosphere.

The BGM uses “iLY” from Number_i’s album “No.I.” It’s a gently soothing, mid-tempo ballad that showcases a different kind of charm from their previously talked-about tracks.

Pink Strawberry Chocolate FridayNumber_i26rank/position

Pink Strawberry Chocolate Friday

This is a solo track by Shiyoh Hirano.

Centered on the sweet, bittersweet memories of a past love, it conjures scenes like walking hand in hand along the railway—just like a moment from a film.

The structure is superb, unfolding from rap-like spoken lines into a beautiful chorus, and his husky, gentle vocals further heighten the song’s melancholy.

The track is included on the album “No.Ⅱ,” released in September 2025.

When you want to quietly look back on an old love, listening to it will surely keep you company.

Romeo and JulietNumber_i27rank/position

Romeo and Juliet

This song starts with a cute-sounding intro, so compared to other Number_i tracks, it gives a different vibe.

The chorus is especially straightforward and is melodic rather than a rap.

The A section and rap parts are generally low—around A3 to E4, I think.

The highest notes go up to about D5, but low-voiced male singers don’t need to worry that it’s “too high to sing.” If you like rap styles, this is a track where you can enjoy both rap and melody, so definitely give it a listen!

The continuation of the dreamNumber_i28rank/position

The continuation of the dream

Number_i is drawing attention for their sophisticated dance performances and genre-defying musicality.

While many of their tracks lean heavily into hip-hop, this piece is perfect for those seeking a gentle sound that stays close to the heart.

It’s a ballad that closes out their mini-album “No.O -ring-,” released in May 2024, and is also known for being produced by Yuta Jinguji.

Its poignant world—overlaying rainy scenery with the continuation of a dream—quietly seeps into the listener’s heart.

The lingering aftertaste, deliberately placed at the very end of the album, is superb.

On a night when you want to forget the busyness of daily life and relax, take your time and really listen.
