It should be noted that there is one problem for scratching of CDs to which age has little effect. The flimsy cases the CDs are placed in. Some of them allow them to slide around inside the box really easily due to a lack of decent gripping mechanism, or alternatively the gripping mechanism shatters into many tiny pieces quite easily (often pre-purchase, I've noted with annoyance) and the discs are damaged by these tiny pieces. Some casing is good, some sucks.
