D-51 Popular Song Rankings [2026]
I won’t forget.D-511rank/position
A number with a reggae-tinged rhythm and lyrics packed tight with little everyday joys that make your heart skip a beat.
The words seem to speak on behalf of parents raising children, and parents currently in the thick of childrearing will likely find it especially moving.
From a child’s perspective, too, it’s a song that reminds you of the gratitude toward your parents that’s easy to forget amid the busyness of daily life.
With its simple, familiar melody and message of love, it might be a great listen at life’s milestones.
NO MORE CRYD-512rank/position
A motivational song that became a huge hit as the theme for the second season of the drama Gokusen.
Many people are sure to feel nostalgic.
The C-melody in particular involves frequent switches between chest voice and falsetto, so it’s recommended for those who are good at falsetto.
The repeated phrases in the chorus also make it crucial to see how accurately you can stay on pitch.
Also, the long G4 note right before the chorus jumps up suddenly, so be careful not to strain your throat by pushing your voice all at once.
If you sing as if you’re running up toward that G4, you should be able to nail the timing.
Keep your facial muscles lifted throughout the C-melody when you sing.
BRAND NEW WORLDD-513rank/position
Starting with lyrics that powerfully rally those who fight, “BRAND NEW WORLD” can be called a fiery anthem that reaches everyone in sports and in any scene of struggle.
D-51, a J-pop male duo consisting of YU (Yu Uesato) and YASU (Yasuhide Yoshida), began their career in 2003.
Their sixth single, “BRAND NEW WORLD,” was originally the opening theme for the TV anime One Piece.
Its bright, up-tempo sound and lyrics about pushing forward without giving up perfectly match the feelings of those working hard in clubs and competitions, as well as those cheering them on, making it beloved as a fight song.
AlwaysD-514rank/position
A vocal duo by YU and YASU, D-51.
Their song “Always” was also used as the theme song for the film Always: Sunset on Third Street.
The lyrics are written around the theme of “things that never change,” with a warm, gentle feel that evokes nostalgic scenes from childhood.
If you listen to this song while watching the sunset, it might make you want to go back to your hometown.
The melody originally came first, and from there they read the film’s script and crafted the lyrics.
It’s a perfect match for the world of Always: Sunset on Third Street, isn’t it?
Foerver FriendsD-515rank/position
“Let’s stay friends forever”—that’s not something you can easily say out loud to a friend.
But everyone feels that way, and D-51’s “Forever Friends” puts that feeling into lyrics.
It’s a song you’ll want to listen to while soaking in all kinds of memories with your friends—like the memories that pile up as the seasons change, or the words a friend offered you in tough times.
Even friends you’ve grown distant from because your circumstances changed—listening to this song might make you think, “I miss those days.
I wonder how they’re doing now?” and give you a reason to reach out!
Forever FriendsD-516rank/position
I felt this song has a deep flavor because it lets you deeply sense the feelings of a man trying to build a relationship with a friend.
Since it has a somewhat calm vibe, I think it brings a sense of reassurance when you listen to it.
Listening to this song made me realize once again that friendship is something unchanging.
Wonder LoveD-517rank/position
The B-side track to the 2004 single “Dreamin’ on.” A music duo from Okinawa formed in 2003.
Their unit name was inspired by a locomotive, but in an interview they said they chose it because they liked the way it sounded, only learning about the locomotive afterward.
With a rhythm that evokes a marching tune and a very light step, it really lifts your spirits.
