superglue against digital copying
Prelease versions of a couple of CDs sent to reviewers by Epic Records used a creative approach to try to combat piracy. The CDs shipped inside of Sony Walkman's that had been superglued shut. Headphones were also superglued into place, to prevent them from being replaced by connections to recording devices attached to the Walkmans. Advance copies of CDs are the likely source of songs from a few albums that have appeared on file trading services before the albums were actually released.
