Thank you, for the response!!
This cd is called the Undertaker. Prince wanted to release this one in a small amount. The record Company did not want hem to release it, because of 'overkill' of releases by this artist. Then some cd's were made unplayable, in the way I described.
One response mentions 'Goop & Gojo'. What is this, exactly? Some sites mention Goo Gone, as a possible product to remove it...
I have also seen somebody talking about using a laser. Does somebody know something about this possible alternative?
