I decided at long-last to finish ripping the final few CDs from my collection into my computer. After several passes at the collection the last few years, the only remaining titles left were the majority of my Live Phish collection. The main reason I put them off is because they're all multiple disc sets and therefore time consuming to rip.
The original set of twenty albums came in binder pages loaded into cardboard sleeves. As those sell, the repressings are in regular quad cases. I had noticed a couple of years ago that some of the binder pages had started to leave a little bit of goo on the discs. It was only one or two of the set and so I wiped it off and didn't think much of it. I pulled the full set off the shelf on Thursday, pulled the binder page out of the first sleeve to note that it was wrinkled. I opened it up and the plastic has begun to break down leaving a massive amount of goo on the discs, which when it has sat long enough, is eating through the discs and into the foil layer, making the discs unplayable.
