How to restore itunes library after updating itunes
The XML file can be copied to your desktop and back to your i Tunes folder to rebuild your library and playlists without any data loss. For Macs, click the "Finder" icon and click the "Music" tab on the sidebar.
Double-click the "i Tunes" folder, and drag the "i Tunes Library.xml" file to your desktop.
But it is not the disaster that it may at first look like.
(added 0840): For the sake of completeness, I should point out that the i Cloud icon with the broken lines shown above indicates a track which is being transferred to i Tunes in the Cloud, typically seen when you first subscribe to Apple Music, or when you have ceased subscribing.
If you, like me, had a three-month trial of Apple Music and did not renew it, or have cancelled your subscription to it, your i Tunes Music library is possibly left in something of a mess.
One user claims that his trial of Apple Music has resulted in the loss of many tracks, and all sorts of other problems.
To that, the i Tunes guru at Macworld has asserted that cannot be the result of cancelling his subscription. As usual, the truth probably rests somewhere between these two extremes.
I have not seen any tracks deleted, nor my original home-ripped tracks lost, but at the same time Apple Music did not restore the status quo.
