@spiritofradio - Thanks for the link. Per the article, about 22-24 minutes per side before there is any effect on SQ.
So, at least some of the offending albums had some "extras" thrown-in to make the 4 sides at least reasonable long. Still wish they would have just put the original content on 2 sides (or 3, if 2 would have been over about 23 minutes per side).
Anyone have any 3 sided records with cool artwork pressed into side 4?
