Just a little of bit of advice with people having trouble with file numbers
Just for a instance say one or many of your files are currupt and your books are printed up with the number in place , reimport song or go to a better duplicate song get a Hex editor off the net there free, open up the file and you will see the number that is assigned to that song simply change that number to the one you want hit the save button it will update the song, rebuild song data base and thats it ,Ive done this because some versions of the songs are totally different from others DONT FORGET TO ERASE BAD FILE you cannot have two files with the same number hope this helps someone
