Also, would you like to explain your published experiences on the effect of crystals in the room ??
I would, but you would just call it jousting.
There is a tremendously large part to tweaking where some proponents will toe the line so long as they are told by others what to hear, but as soon as someone tells them to think for themselves, or goes some place new, they can't go there.
So, to continue jousting:
If you believe that there are magnetic properties 'hidden' in a CD or its label, if you consider the mass of the material that is magnetic, it is quite low.
The reason I mention that is with such a low magnetic mass, you can expect to see magnetization/demagnetization changes quite quickly.
Quickly enough that you, if you are of that persuasion, can leave the 'on deck' CD on your magnet getting ready while you listen to the current CD. You can also readily compare directionality of the treatment!
The subjectivists will likely toss off the connection between the mass one wished to magnetize or demagnetize and how long it would need to be treated as just another 'objective' observation intruding on their jollies, but for others, it shouldn't take all that long to investigate for themselves.
Also on the plus side for magnetization: With demagnetization, one will have to keep undertaking the process over time. With full magnetization treatment the effect, as you know, can be VERY long lasting - magnetization is better retained than demagnetization!
You can demonstrate this on your own at home with a magnet and a needle or screwdriver!
