Vocaloid songs that start with 'O'
If you’ve come here, chances are you like Vocaloid songs.
It’s been a long time since Hatsune Miku’s debut in 2007, and countless masterpieces have continued to be born.
In the meantime, the Vocaloid scene has seeped so deeply into the times and culture that we even have the term “Vocaloid-native generation.”
Now then, what I’m introducing this time is a selection of Vocaloid tracks whose titles start with the letter “O.”
Be sure to read to the end and find a new favorite track!
