Recently, I've taken it upon myself to add English translations or romanized versions of Japanese anime soundtracks. Mostly for my personal use.
I'm wondering how the artist field should be filled out. Specifically, the character and voice actor info.
For example, Oracion uses CV before the voice actor name, "Character name (CV: Voice Actor)", but that's also present in the original Japanese credits.
In Utamonogatari: Monogatari Series Theme Songs Compilation Album, the Japanese credits lack the CV; they're just "Character name (Voice actor)"
Should it be kept in the same style, or should they be unified? I couldn't find any guidelines on this.
