What they should be doing is making the CDs more attractive to computer users by using the Enhanced CD stuff, so when you put it in the computer you get lyrics, photos, extra personal bits like you suggest. I hadn't thought of them varying this component to create collectibles, but that makes even more sense.
Almost all CDs published in the UK have these on, and production houses have got the cost down to a few thousand a CD to do it. (It's even cheaper if you do it yourself).
Add value instead of subtracting it.
