Music fans once had a reputation for obsessively assembling their CDs into neat alphabetised rows, but the days of the cherished CD collection seem numbered as the iPod generation puts all of its music on to computers.
The charity Scope said today that its 300 stores were being inundated with donated CDs, as more and more people trim their collections - or even get rid of them altogether to free up space.
Meanwhile, the online auction site eBay invoked memories of EU food mountains when it said a "CD mountain" was fast being created and that the average person could make hundreds of pounds by selling their collections.
After surveying 1,000 UK households, eBay estimated music from CDs worth £17.2bn will have been transferred to MP3 players in Britain by December.
The firm calculated that if every CD in the UK was sold second hand, the value would be £52bn.
It said there were 7.38 billion CDs in the UK, with an average of 164 CDs per person.
