As long as you load the song after you replace the file so that MobileSheetsPro detects the change and updates the database, I think it's fine to do that. If you don't load the song though, then the database will be out of sync with the file on disk. If you are loading the song and MobileSheetsPro is not updating the file size in the database, then that's a bug I will need to fix.

EDIT:
Looking through the code, it does appear that I should be updating the file size in the database. So hopefully you are seeing that happen.
