No You're Not Crazy, Music Was Being Deleted From Your Apple Library
It's comforting to know I wasn't going crazy going crazy. Apple recently admitted to deleting parts of my already purchased library.
Following the launch of Apple Music last year, reports started rolling in of already-paid-for music mysteriously disappearing. Apple has since owned up and announced they will be releasing an update this week to fix the problem. Though they’re unable to reproduce the problem, Apple is releasing an updated version of iTunes that "includes additional safeguards" so the issue doesn’t arise again in the future.
The bug went unnoticed by Apple until big-time composer James Pinkstone wrote an open letter (one of many) to the company complaining about 122GB worth of music files going missing from his computer. Some of the music deleted included Pinkstone’s original compositions, which he then accused Apple of “vastly overstepping its boundaries.”
Though I’m unsure who to be more grateful for, I ultimately wanted to know the root of the problem. And alas, we have answers. It has to with the way music syncs up to the ever-mysterious “cloud.”
"Apple Music subscription allows iTunes to scan the user's mp3 and wav files. It matches them with Apple's own database, and deletes the original files from the internal hard drive. Essentially, Apple stores all the files on cloud, deleting them from the device, inadvertently forcing the user to have a data connection to access their music on Apple Music or iTunes." – A Statement by Apple to iMore Technologies
More of Apple’s statement has been posted below and although they insist that a fix for this problem is on its way. They also recommend users to back up their music on external devices, in case an issue similar to this happens in the future.
"In an extremely small number of cases users have reported that music files saved on their computer were removed without their permission. We're taking these reports seriously as we know how important music is to our customers and our teams are focused on identifying the cause. We have not been able to reproduce this issue; however, we're releasing an update to iTunes early next week, which includes additional safeguards. If a user experiences this issue they should contact AppleCare."
