One of the victims was supposed to be CD singles in cardboard sleeves. I'm pretty sure mine are all OK. Of course the furore assumed that we would all be still wanting to play our CDs in 25 years time, who would have realised at the time that CDs would become play/rip once items.

...tend to go all 'marbled' after a while (they still play okay, though).

Was rather flush at the time so bought the entire David Attenborough wildlife range in 2004 (actually was at the counter in HMV when I got the phone call from a mate to say John Peel had died, so that dates it specifically for you).

Finally got round to a particular series late last year only to find that the metallic layer of the DVDs had several rivulets of cracks and that the whole silvery look had become a kind of copper rainbow hue.

Got in touch with 2/Entertain who replaced the discs in the whole of that set. It took some pushing, mind.

I had a friend of mine make some compilations in the 3rd year at seconday school (8 years ago). They were cheap copyable CDs. They've since gone a little bit brown on the top side, but still play beautifully, aren't warped, and now emote times of yesteryear.

My vinyl of a similar age, however, has got a little bit bent and so wurbles. Bad times.

Bought in 1990. Well looked after. No scratches or strange marks. Now completely unplayable.
I've gone through four copies of this album.... two on vinyl (one scratched to buggery, one stolen) one on cassette ('nuff said)and now this.
