I just had a bunch more tracks disapear. This is my second complaint, and since then I haven't seen a single post from Apple revealing any kind of resolution.
So here's my announcent for anyone that will post in this thread:
-Apple knows that they cannot do anything about the deleted tracks caused by the bug in iTunes, so they will ignore helping anyone in this thread.
-Backups may not matter in this case depending on when they happened. The problem with this bug is there is no way of knowing about new missing tracks amongst the maybe thousands of tracks in your library. So if you perform a backup when you have new unknown deleted tracks, it will simply copy over exactly what you have on your primary drive.
-No one has found a way to resolve this. There is no solution.
-Apple has lost control of the quality of their software lately. This is why people have stopped using Maps and Final Cut. Like Maps and Final Cut X, iTunes is now crap. Do you really want a program that will randomly delete songs that you paid money for? No. It's time to use something else. 😉
