LOL. We still buy CDs (and having recently bought this beauty in red - https://www.project-audio.com/en/product/primary-e-phono/ vinyl) to play via our hifi. I also have a few hundred LPs and singles from my teenage years.Wow you’re brave! Did you not feel like it’s a waste to delete? I’ve probably spent thousands on CDs in my lifetime plus with Apple Music I was just listening to the same stuff I owned but paying for the privilege.
I agree about iTunes Match potentially being switched off. I can’t even find the option to buy it on my iPhone so I’m guessing it’s Mac only
I don't really find it a waste - obviously, I was having to rip stuff to my MacBook Air M1, using an ancient external CD drive coupled up to a USB to USB-C adapter, and rarely played music from the MacBook so it was just taking up a lot of storage. It was a pain to sync to my iPhone and my wife's iPhone too.
I've tried iTunes Match more than once to my regret, and found it a pain. It doesn't work in quite the way I expected and doesn't help if you want to share music with other people in your household.
