Spay for CD

As far as I know, no one knows(thus far) of what a magnetic field is composed. Like gravity, the THEORY is it’s a deformation of space/time (or not *) , caused by the presence of matter, coupled with the, "quantum spin"(which is itself an inaccurate term) of certain particles. Like so many things in our universe, magnetism’s effects can be measured, but- the actual mechanics of it’s operation remains a mystery.  As far as concluding that debate, one may as well try to nail Jello to a wall. Even WITH a knowledge of Special Relativity, Quantum Mechanics, Physics(ie: QED, the "Jewel of Physics") and their attendant mathematics. (Let’s see: should I mention either electroweak theory, or, "virtual photons"? NAH!) As I’ve said, so many times, "No one has all the answers." My apologies, to the OP, if I’ve caused a ripple in this thread’s continuum. (https://www.scientificamerican.com/article/do-electric-charges-and-m/) (* https://physics.aps.org/story/v7/st27)

Had anyone else ever tried this stuff? https://www.musicdirect.com/equipment/ultrabit-platinum-clean-disc-combo  If so, what were your impressions?

A couple things, I just found, that may be of interest to some(SORRY again, OP): https://www.youtube.com/watch?v=cYA0bntrjsk(comments notwithstanding) and https://www.youtube.com/watch?v=wMFPe-DwULM(I love this guy!)

What magnetism is composed of is irrelevant. All you need to know is that demagnetizing CDs or LPs improves the sound, or interconnects. So I guess we can close this case. 

I couldn’t agree more! Regarding my last post: I just thought you may be interested, in what your favorite physicist(my assumption) had to say on the matter! You did pose the question, " Just one more thing. The web site you linked to edu Illinois Physics forum of some kind, as I recall, made some statements that magnetic fields were composed of photons. Since magnetic fields are stationary how can they be composed of photons that move at lightspeed?"
