It’s been a long time since Hatsune Miku’s debut in 2007, and countless masterpieces have continued to be born.

Vocaloid songs starting with “O” (181–190)
Birthday SongNishimori Riyon

It’s a very simple birthday song that proceeds almost entirely with just piano and hi-hat, making it perfect for singing a cappella at birthday parties.
Another recommended point is its easy-to-listen, nursery rhyme–like sound arrangement.

Created by Den-ǂ-Whale, the piece “Osoushiki” was released in January 2025.
True to its title, the lyrics take a funeral as their motif, quietly posing questions about ghosts, memories, and the afterlife.
They weave reflections on the deceased together with rural landscapes and ritual scenes, evoking a curious sense of nostalgia.
Its pastoral, airy musicality is also compelling.
It may be a good listen when you’re in a contemplative mood.

The Sun Above and the Gutter RatUtsu P

“The Sun and the Gutter Rat” delivers an aggressive message: we won’t be forced to work hard just because “the sun is watching.” With dark yet radical lyrics that liken the self living in the shadows to a rat, paired with a rock sound, the song and its video are hooking audiences around the world.
It was produced by Utsu-P.
OVERsake P

This song is perfect for spring, the season of farewells.
It’s a Vocaloid track by ShakeSphere, also known as Sake-P, who excels at R&B sounds.
Released in 2009, it quickly drew attention.
The stylish chord progressions and the mixing that gives the vocals a wavering feel are particularly striking.
Although it’s about a heartbreaking breakup, it can also lift your spirits, so it’s recommended for anyone who’s recently gone through a breakup and is feeling down.
alternatekeeno

“Alternate” means “substitute.” This song is about a woman who keeps dating someone even though she knows she’s only a substitute for the person he can’t forget, which makes the title stand out even more, and I think it really hits you when you’re listening and crying.
