My CD collection (1200 and growing) began in the early 80's. I have never had a CD develop problems. I am very particular about how my CD's are used. Never in the car, always returned to their case, not exposed to direct sunlight, etc.
Last week I saw an artical on ABCnews.com about a collector who was experiencing major problems with CD's that previously were OK. The article didn't go into how this collector treated his CD's. The thinking was that perhaps flexing the discs to remove them from their case or general rough handling was fracturing the thin protective label side coating thus allowing oxygen to react with the aluminum substrate. I have some cases which really hold the CD tight, but I am carefull not to excessively flex the discs.
