A couple of the CDs I bought at Ameoba had blue-and-grey "Previously Played" stickers on them. Silly me; I thought they were there as a customer service, letting me know why they were mine for three dollars and ninety-five cents. But now that I've been able to inspect the cases more closely, I know the truth. They've been slapped on to cover up the "For Promotional Use Only" stamp the record company slapped on.
