SEKAI NO OWARI Popular Song Rankings [2026]

Biological FantasiaSEKAI NO OWARI71rank/position

Seibutsugakuteki Gensoukyoku

Just from the title alone, it’s easy to imagine that “Biological Fantasia” is a song imbued with a grand theme.

Released in May 2012, this track prompts you to rethink the meaning of existence and life.

Its fear-inducing, high-impact sound, addictive melody, and thought-provoking lyrics that aren’t exactly sing-along-friendly—all of it leaves a strong impression.

Sing it at karaoke and you’ll definitely grab everyone’s attention! There aren’t any especially high notes, so even those who’ve given up saying, “I’m not good with high notes, so I can’t sing SEKAI NO OWARI,” should give it a try.

Mermaid RhapsodySEKAI NO OWARI72rank/position

Mermaid Rhapsody SEKAI NO OWARI Osaka Nanko Free Live

It drew attention when it was chosen as the theme song for the film.

The song is based on the theme of a mermaid, and its richly fantastical storyline is a highlight.

With the sounds of bubbles popping and a harp used throughout, it’s a very pleasant piece to listen to.

DoppelgangerSEKAI NO OWARI73rank/position

Doppelganger

SEKAI NO OWARI’s masterpiece “Eye.” It’s an album that ventures into genres they hadn’t explored before, and one of the tracks included, “Doppelganger,” is characterized by a style that incorporates jazz elements.

It’s not hardcore jazz, so the rhythm is easy to follow, and the vocal range isn’t very wide, making it a song that even those who aren’t confident in singing can try.

There aren’t many long notes either, so even if you can’t do vibrato, it’s still easy to make it sound good—another point that makes it singer-friendly.

GoodbyeSEKAI NO OWARI74rank/position

Goodbye

The masterpiece “Lips,” released in 2019.

This album is known for featuring many tracks with a wistful tone, often evoking elements of early Heisei and Showa-era pop.

Among them, the song I especially recommend is “Goodbye.” It’s characterized by a chord progression similar to the TV commercial “Isuzu no Truck,” and the entire piece is guided by a relaxed rhythm and a grand melody.

The chorus gradually raises the voltage and is easy to sing in tune, so be sure to give it a try.

EdenSEKAI NO OWARI75rank/position

Eden

The song Eden, included on the album Eye released in 2019.

Among SEKAI NO OWARI’s works, this is a particularly popular acoustic number, characterized by an overall highly languid mood.

With its relaxed rhythm and narrow vocal range, it’s a very approachable piece even for those who struggle with singing.

Because the arrangement is simple, the one tricky point is that it leaves little room to disguise imperfections in the vocals.

If you tend to make mistakes when performing in front of others, start by thoroughly learning the vocal lines and rhythm.
