'Performer' and 'Conductor' tags appear to be interfering with retrieval of 'Artist' or 'Album Artist' data.

I see there have been a few issues with music tags in the past and heartily agree with @TheOldPresbyope that this whole thing is a dumpster fire with no standards. But right now (release 8.0.2) it appears that any files that have a 'Performer' or 'Conductor' tag defined end up being dumped in the 'Unknown Artist'/'Unknown AlbumArtist' category in tag view. This occurs with all of the choices in the 'Tag view artist' field. 

My music is stored on a USB drive connected directly to the Pi. If I edit the file tags (using MP3tag 3.14 on a PC), solely remove the 'Performer' or 'Conductor' tag and update the library then the album turns up correctly listed under the relevant artist in tag view.

I should note that this is happening on AAC files (with the .m4a extension) that have been tagged using MP3Tag.

The issue is being caused by having all the performers as a comma separated string stuffed into a single performer tag.
