Expanding on the question, being a retired IT director, one of the reasons for my not letting go of the CDs, is back up paranoia - the doomsday scenario of the vault crashing along with the database, and the restore doesn’t work. Note, that I know the vault’s backup/restore works fine because I had to use it to restore all my CDs when my first vault failed and was replaced with a new one. It restored everything perfectly to the new vault. (I also copied the “music“ database from my Mac to an external drive as well, talk about paranoia.) Add to that the emotion of letting go of years and years worth of CD collecting has, so far, prevented me from getting rid of them.
I have no interest in spending the time to post many of them on Discog, nor do I care about getting any money for them. I know a few friends and family who would be happy to take several in my collection.
I guess, for me, I have to come to a point where I could, emotionally, just “let go“. I’m sure it would be easy once I get there. I’m assuming many of us are in the same position.
