Help coming up with a Virtual Tag formula

[dulfbarglin]

I'm trying to figure out how to use Virtual Tags but I have no programming experience. I want a tag that only displays artists that are main, album, or guest artists. However, I'd like to see any track they're listed as a performer or remixer on under the resulting entry. So if I have an artist that only has performer credits I don't want that to show up but if they have Artist, Guest Artist, or Album Artist credits show me everything they're on, including Performer. Is that possible?

That's probably not possible with the current features.  Virtual Tags can only look at a single file; this would require analyzing multiple files.

One alternative might be to assign performer credits to a custom tag, like the available Musician Credit List tag under Custom Tags.
