I'm trying to get mp3tag to list song performers in individual tag panels. I've created the fields (PERFORMER\_01, PERFORMER\_02, etc.), but different files have different numbers of performers, so I'm struggling to tell "Filename - Tag" how to read the filename structure.
EXAMPLES:
(Performer 1, Performer 2, Performer 3,...) \_ (Artist) \_ (Album) \_ (Track #) \_ (Track Title)
Jack White, Meg White \_ White Stripes, The \_ Elephant \_ 01 \_ Seven Nation Army.mp3
Bon Scott, Angus Young, Malcom Young, Cliff Williams, Phil Rudd \_ ACDC \_ Powerage \_ 04 \_ Riff Raff.mp3
Notice the different number of band members between these tracks. I'm stumped as to how to tell mp3tag to fill in each "Performer" tag -- one per comma -- and move onto the "Artist" tag when it hits " \_ " in the filename.

You are asking for a solution where different numbers of comma separated performers would be filled into the corresponding field names, right?
For your example something like this?
(Just to understand your question)

Yes - This is exactly what I'm looking for.
But what if the song has less than 5 performers?

Would it be helpful to first get 1 x
`MY_PERFORMERS`
field from Convert Filename -\> Tag with
`%MY_PERFORMERS% _ %ARTIST% _ %ALBUM% _ %TRACK% _ %TITLE%`
and fill it with ALL your performers separated by a comma like this:
and with the Quick-Action "Split field by separator"
you could split `MY_PERFORMERS` into
several MY\_PERFORMERS like this:
Or do you really need different numbered field names for different artist names?

They way you've done it is probably preferable. Thank you.
