I thought of going through the remainder and picking out the ones I might still want to play- but I'd be fooling myself if I did. I hardly ever listen to music. I prefer everyday noise. Occasionally I'll click on something that's been posted to YouTube.
What does one do with unwanted CDs? Charity shops still carry them but I don't think they particularly want them.
There's a cardboard box in the spare room cupboard full of 78s- unplayed and all but unplayable. I suppose the CDs will join them. Someone in the far future may stumble upon them and go, "Oh look!"
