Howdy! I also use MusicBee. I’ve written a script that will (provided things are entered correctly in the database) tag feat artists, remixers, etc to appear as multiple artists in MusicBee, and also insert the Display Artist field that MusicBee uses. (Note this also relies on the Standardize Feat. plugin.)
This is my script:
$if($in(%artists%,;),
$set(DISPLAY ARTIST,%artist%)
$if($in(%artist%,feat.),
$set(artist,$rreplace(%artist%,\\sfeat.*,))
$setmulti(GUEST ARTIST,$replace(%artists%,%artist%; ,))
,
$copy(artist,artists)
)
,)
$if($in(%title%,mix by ),
$if($not(%remixer%),
$set(remixer,$rreplace(%title%,.*mix by ,))
$set(remixer,$replace(%remixer%,\),))
,)
,)
