This has been a complaint of mine with music programs for, literally I think, decades. If you need to overlay some metadata that's fine, but in that case at least index it by header checksums or something, not by file names and paths! (Especially not absolute paths.) Please respect my organizational choices and make sure I can rename and move things around without worrying about "ruining" the database.
