CDs do emit music over higher frequencies stronger than vinyl. That is not a lie.

The lies about lies are lies.

Some people can’t hear it. I can. I can hear a TV when it’s on, and I can hear harmonics of Wifi, so when I say I know it’s true- I know it’s true.

They -can- emit higher frequencies with better fidelity (and DR), however that's a product of mastering the CD, not something that need occur in the CD by its very nature. So the way you're stating it is incorrect. A CD can replicate anything a cassette/vinyl can do (that is perceptible by human hearing). Now whether industry respects that or not is up to the company/band/whatever making the CD and what they choose to emphasize.

And I know Wifi is electromagnetic radiation, so there must be some phonon interaction somehow.
