Hit and popular songs by LEON (Léon)
LEON, a VOCALOID-compatible singing voice synthesis software, was first released in 2004.
LEON (male voice) and LOLA (female voice), among the very first VOCALOID products, were developed in the UK and are designed for English, but it seems some producers have devised ways to make them sing in Japanese as well.
The voice source is said to be a British soul singer, but LEON can handle a wide range of genres beyond soul.
It was originally developed with the goal of handling backing vocals, but nowadays a scene has formed where Vocaloids sing as the main vocals.
Now then, please listen to the singing voice of LEON, the origin of Vocaloid.

LEON's famous and popular songs (11–20)
Brutal LEONLEON / Masaop (True Blue P)
This is the opening song of the BL game “Kichiku Megane” sung by Leon.
It has become a male VOCALOID assignment piece.
It seems Choiwaru-P’s influence was quite significant.
The tuning is well done, but it’s hard to focus on the singing because of the video.
Sweet InsanityLEON/D.F.K.Soundsystem

This is my first post under my hardcore-music alias, “D.
F.
K.
Soundsystem.” I usually upload as Daifuku-P.
It’s a cool and stylish drum and bass track featuring Leon.
The vocals come in at around 1 minute 40 seconds.
Heart SutraLEON/aushi

In a way, the last song is an ideal pop song.
It sings about everyday life, and it’s become the kind of track I want to listen to before heading to work each day.
For office workers around the same age, I think playing it during breakfast will help you power through the day.
Galaxy Express 999LEON/cl1

This is a cover of Galaxy Express 999.
It uses VocalPhonetic and sings smoothly.
The illustration is borrowed from Choiwaru-P, but the content itself is a thoroughly serious work.
Leon’s deep, gritty singing voice suits it well.
Pop KeyboardLEON/kotaro

As the first-generation overseas Vocaloids are being discontinued, there will be a three-day farewell project uploading original songs by LEON and MIRIAM.
These are included in the album “I do nothing but daydream.”
nuclear wrapLEON/matrox_revo

A track that showcases the shining vocals of LEON, the origin of Vocaloid.
This piece sets mondegreen-style lyrics to Touhou Project’s “Reach for the Moon, Immortal Smoke,” and its appeal lies in an astonishing vocal performance that handles high-difficulty, rapid-fire passages.
While the tune is pop and catchy, its synth-bass-like breadth of range and speed leave a strong impression.
It’s a song that fully brings out LEON’s flexibility and charm.
Highly recommended not only for Vocaloid fans but also for fans of the Touhou Project.
Enjoy LEON’s singing while experiencing the diversity and creativity of Vocaloid music.
LEON's Masterpieces and Popular Songs (21–30)
Tear off your tits.LEON / Slightly Bad Boy P

A track that shook the Vocaloid scene! Its humorous lyrics and distinctive melody are irresistibly catchy.
When it was uploaded to Niconico in January 2008, it quickly gained popularity.
While making the most of LEON’s unique vocal timbre, the arrangement shines by carrying over the original song’s comical charm.
The fresh idea of covering an anime character song with VOCALOID also became a hot topic.
This work fully showcases Choiwaru-P’s technical skill and sense of humor, and it hints at new possibilities for musical expression using VOCALOID.
Perfect for blowing off steam or when you want a quick laugh.
Be sure to give this addictive tune a listen—you’ll find yourself humming along before you know it!
