Here we go again, Ive just updated to 12.3.1.23, and once again ALL my non iTunes purchased songs (thousands and thousands of them) are gone! While I used your wonderfully helpful article in Jan 2014, this time around there are no recent .itl files or .tmp files for that matter.
In fact there is only one old .itl file from the last time I undertook this process, yes you guessed it in Jan 14. I have two questions, 1) why do Apple do this? They don't own my other music? And 2) why are there no other .itl files between Jan 2014 and now Nov 2015?
Please help.
And this will be the very last time I ever take an iTunes update. If it ain't broke, Apple will make sure it is.
