best advice would be to check your browser history to try to find the download page (whether from mega, mediafire or else), and see if there is any occurence nearby in said browser history of an FFshrine thread. or of another forum/site where you DL stuff. chrome is especially good at this. a bit slow but good.

What soundtracks?

what having filenames? sometimes here using same format, so can knowing pass if knowing name

I don't remember what they were I just have the rar files
