However, to be honest, I do not know how much I value the physical collection I have put together. I have sold records in bulk before and regretted it. I ended buying some back, unfortunately in worse condition than my originals and more expensive too. So don't want to go there again.
What I do know is that I can't rely on the likes of Spotify, what is in their library today maybe gone or changed tomorrow. So much on internet radio though as you say, so it's very easy to listen to that all day and enjoy the gems you come across that way.
You and your system has given me food for thought though. Many thanks and enjoy the music.
