I too had a collection I couldn't really manage or listen to. about 2250 CDs and the samenumber of LPs. I got rid of most of my vinyl through a dealer friend, leaving about 400 LPs, which is more than enough, though I am back to buying a few again, I'm incorrigible. That was mainly to avoid laying too much of a burden on my kids, to get rid of all my stuff, when I finally fall off my perch.
I was planning to sell my CDs, having loaded them onto an Innuos Server, but lost the will to live trying to set up an Amazon private sellers A/C. Then it struck me, children today think money comes from a magic money tree. So I plan to give my CD collection to my grand kids, when they are a bit older. Have you noticed how much second hand CDs are selling now. Many of mine seem to be worth north of £20. I reckon my collection is worth about £20000+. They can sell them and put the money into their college funds.
