I have hundreds of CDs burned to my iTunes Library, and lots of individual songs I bought from the iTunes Store over the years.
I have all of my music on my iPhone and that's where I listen to it mostly.
I just noticed in the iTunes Library, there are tons of songs missing.
Here are some screen shots (below) ... every song with a "!" icon next to it is missing, not on the hard drive.
There are no other problems or missing files on my MacBook.
In some cases ... David Bowie "Tonight", Pearl Jam "Ten", for example ... the entire album is gone.
I'm not an Apple Music subscriber, but I did try the three month trial when it first came out.
Did Apple do some kind of "sync with Apple Music" on my iTunes Library which caused songs to get replaced with their copies and, in some cases, removed?
Any ideas what happened here?
