Therefore, Zun is called "God Lord"
Most of the game programming, personnel design and BGM are created by ourselves. Shanghai Alice Magic Orchestra is just a registered trademark.
For various reasons, the Oriental series has been attracted by various secondary fans, including games, music, comics, animation and so on. It can be said to be a great miracle in the same field.
And music is naturally the most important piece.
The endless music you mentioned is mostly original music adapted from ZUN by various fan clubs.
Because there are too many download addresses, it is impossible to list them one by one. Most of them will be published in animation music-related forums, which need your own attention.
If you want to have a general understanding of the East, you can go to Baidu Encyclopedia, look at the Oriental Project and look at the Oriental Wiki (although it will be a bit confusing at first).
If you want to know more. . . The east is profound, I really don't know when. . .
