Why interpretor instead of author in a play-list?

Thanks for these screenshots.

For each track, MinimServer sends all available information (Artist, AlbumArtist and Composer) to the control point and leaves it to the control point to decide what information to display.

Synology Media Server sends only Artist information with the track. This is why you don't see AlbumArtist information when playing the track using Synology Media Server.
