Today I tried to select and delete two or three albums from the middle of my music library on iTunes. After highlighting them and selecting delete from my library, I noticed that everything before what I'd selected (or meant to select) was gone. I mean, 1,000s of songs from a library I'd built up over the last 15 years or so. Including a tonne of great music that I'll admit I don't know the details for and the rest will take me years to remember. I was sure that I could restore my library somehow, but no. A long chat with apple and a bunch of research later and apparently once you press 'delete from iCloud library' it's gone forever, no back-up or file save will help you. I know this is my mistake, but surely Apple should have a safety net. I'm really ****ing angry about it.
