I am unsure how to express the album/song artists for a soundtrack release because of two reasons:
The artists are not directly credited in the album. I only found them through external websites that talk about it.
The artists are Japanese, so should I use their name in Japanese characters, or use the Latin transliteration of their names?
This is the album that I am referring to: https://musicbrainz.org/release/aee7d9f9-2db9-40e0-af36-6a7889cb905f
This is the official website of the album:
And this website contains information about the authors:
At this moment, all songs appear to be by 鈴木克崇, 島翔太朗, 中村佳紀 & 植松伸夫, but I don’t know if that’s is right.
