C&K Popular Song Ranking [2026] (21–30)

Deep blueC&K21rank/position

This is a song written by the vocal duo C&K as the theme for The Breakthrough File: Breakthrough Koban.

Conveying that anyone can enjoy their youth anytime depending on their mindset, regardless of age or status, the piece is memorable for its lyrics sprinkled with phrases that evoke the color blue.

With a vibe that blends reggae, disco, and funk, it’s also recommended for those looking for an up-tempo dance number.

In summer, not only the beach but also the many lively and dazzling events like festivals and fireworks make the memories we spend together even deeper.

C&K is a duo of two men, but their voices are so high you might think there’s a woman singing.

Member CLIEVY’s super high-tone voice is a highlight!

In Your WordsC&K23rank/position

This track, with an impressively reggae-like groove, is “Kimi no Kotoba de.” From the very beginning, the beautiful singing voice immediately captures your ears and won’t let go.

The lyrics convey the message that just a single word from you can stir a variety of emotions in me.

It’s a beautiful love ballad that conveys straightforward affection for the other person.

It’s a bittersweet unrequited love song about feelings for someone living far away.

The male duo C&K released it in 2016 as their 14th single.

The gentle sound pairs well with their soft vocals.

This song has become a new wedding staple.

I think the expression “continued →” is lovely.

It’s the song that made me think again, “Oh right, there are six billion people in the world.” When you feel that no matter how much money you’re offered, all you need is that one person, I recommend letting this song ring out in the church chapel in the background.
