I have some albums that have multiple artists but aren’t compilations. Usually they are splits where half the tracks are by one artist and half by another.
I’m wondering if there’s a way to detect this and use it so my path format can include the track artist in the filename only if the release has multiple artists on it? For example Musicbrainz Picard has a boolean variable
%_multiartist% that can be used in the naming formatting for this.
