Common

I recently bought three new Classic pressings, all 200g titles: Norah Jones; Diana Krall; and Tull's Aqualung. All were defective. In examining the vinyl I noticed a threadlike discoloration which was literally stitched into the vinyl. When the stylus runs over this, both channels distort rendering the passage unlistenable. Clearly, Classic is not using virgin vinyl and some form of foreign matter is being added. Dare I consider this might be the labels from old LPs recycled? Anyone else notice this or have similar experience?
