I feel for you. I have a huge storage problem, and my wife is trying to get me to downsize. I did get rid of over a thousand discs in the last 12 months or so, but still have more coming in and removing that many was a drop in the bucket. Luckily my wife hasn’t realized the advantage of streaming in this regards and I’m free from that pressure of her pushing streaming on me!
I do know I need to work harder at divesting myself of all the thousands of discs I know I really can’t justify having and don’t want to burden her and others to dispose of. In the meantime I love my collection!
