So I’m sure this is probably pretty simple, but I didn’t find it quickly searching the documentation or forums so hopefully someone can help me out with this.
I want the folder to be
Artist - Album (year) [format]
with format being one of these three things: [FLAC] [V0] 
V0 and 320 being mp3 bitrates. I found %_filename% which is not quite what I want. This is my current script:
$if2(%albumartist%,%artist%) - $if($ne(%albumartist%,),%album% $if(%date%,($left(%date%,4)))/,)$if($gt(%totaldiscs%,1),Disk %discnumber%,)/ $num(%tracknumber%,2) - $if(%artist%,%artist%,) - %title%
Any help would be appreciated, thank you.
