A photon is massless,[Note 3] has no electric charge,[12] and is stable.
I never said a photon did have mass, or that it had an electrical charge or wasn’t stable. But electrons are carriers of *charge* not the audio signal. The electromagnetic wave that is the actual signal is made of photons. Just like (visible) light but with a different wavelength. Gamma rays, x-rays same thing - Photons with a different wavelength than visible light. The electromagnetic spectrum is extremely wide and includes obviously visible light which is obviously just a very small part of the whole thing. Electrons in the conductor are almost at a standstill, but the music signal is moving at near light speed (since it’s made of photons). That’s what I mean by carrier. The radio wave (RF) does not need a medium in which to propagate, obviously, since it will propagate in a vacuum. Just like a radio transmission to a satellite is comprised of photons. Or an ELF transmission.

Electromagnetic radiation. Now we’re getting somewhere! I am agreeing with that statement. That's what I’ve been saying, that light and radio waves are electromagnetic waves, radiated. The units of measurement for satellite communication transmission is surprise, surprise, EIRP, Effective Isotropic Radiated Power.

Electrons carry charge, whereas the music signal is an electromagnetic EM wave so it (the signal) must travel in a conductor at near lightspeed. In order to travel at that speed the wave must be, physically, photons, not electrons. The electrons in the conductor only travel what a meter an hour or something. If the audio signal wasn't light speed you would hear a pretty big delay for normal phone conversations, no?
