What artist credit should I use for a release where the 朗読 is prominently credited? I was going to use [author] 朗読：[narrator] since I was unsure, but no idea what punctuation is most common. I couldn’t find any examples of Japanese audiobooks in the database that use this style. Most seem to just be credited to a single artist.
This is specifically for Japanese releases. Scans of the release in question can be found here.
