Another important note: There are a couple of features in i Tunes that are on by default on Mac but are normally off on Windows.If you're unfamiliar with them, you probably should have them turned on, as they will help keep all of your music tidy going forward.Below are a number of different suggestions, each with its own upsides and downsides.
The dreaded exclamation points in your i Tunes library!
Edited metadata that doesn't show up outside of i Tunes!
There's at least a few types of information that will be lost in the process, which may be considered valuable bits of metadata for some folks: star ratings, “Loves”, play counts, and date added.
If you can live without that information, this method tries to preserve everything else about your i Tunes music library.
The first thing to note is that this method is drastic, and depending on the types of problems you have with your library, it's possible that you can end up worse off than when you began.
Thus I very strongly recommend that you back up your existing i Tunes folder before going any further, even if it's a mess.i Tunes works really hard to try and fix these problems, but if you're reading this it means that you're running into problems that i Tunes couldn't automatically work out on its own.No matter how your library became a frustrating mess, there's almost always something you can do to get your library happy again.Quit out of i Tunes, then delete any of the following files you saw in the first step: “i Tunes Library”, “i Tunes Library.itl”, “i Tunes Library.xml”, “i Tunes Music Library.xml”, “i Tunes Library Genius.itdb”. Now we're adding everything back into a fresh clean library.Start up i Tunes again, and don't be shocked that your library is completely empty.When you get to it in Finder or File Explorer, you'll recognize it by the files within.
