You can expand the existing list of values at the end of this script
## Void temp tags/variables:
Set "TEMP_Multidisc"
Set "TOTALDISCS"
Set "TEMP_Various_Artists"
Set "TEMP_DiscNumber"
Set "TEMP_TotalTracks"
Set "TEMP_Track"
Set "TEMP_Title"
Set "TEMP_Artist"
with all the tags you don't want.
As @poster write, be careful and don't use a TAB between the command SET and the unwanted Tag.
