If you keep track of the songs that are duplicates as you go, you could cut down on a lot of space by just giving us a list of what songs in the pack should be set for players on other teams / stadium effects. I don't know how many duplicates there are really, but guessing there is a bit from using the packs over the years.
This is exactly what I do. Very time consuming but saves tons of space. I made a song spreadsheet for players and songs, similar to whst MLB Plate Music does
