I just solved this today!
The easiest two solutions would be to use either the Feat. Artists in Titles or Feat. Artists Removed plugins found here.
I however prefer them in the artist tag. What I have done is use this string:
$left($rreplace($if2(%albumartistsort%,%albumartist%,%artistsort%,%artist%),; [^\)]+,), 60)
The if2 will use the album artist (if it exists) before using artist. Typically the album artist will not include the featured artist.
If you are having trouble fitting that string into your script here is mine:
$replace($rreplace(
$if($eq(%albumartist%,Various Artists),
[Various Artists],
$left($if2(%albumartistsort%,%albumartist%,%artistsort%,%artist%),1)
/
$left($rreplace($if2(%albumartistsort%,%albumartist%,%artistsort%,%artist%),; [^\)]+,), 60))
/
$if(%date%,[$left(%date%,4)] )$left($replace(%album%,/,), 70)
/
$if($gt(%totaldiscs%,1),$if(%discnumber%, \(Disc %discnumber%\),),)
/
$num(%tracknumber%,2). $left(%title%,120),[:?"_]+,), , )
This script will give you an output of:
\B\Beatles, The\[1965] Help!\07. Ticket to Ride.mp3 \[Various Artists]\[2005] Coup d'État, Volume 1 Ku De Ta Prologue\(Disc 2)\05. I've Got to Learn the Mambo.mp3
Hope this helps!
