AudioPHILE = audio LOVER (literally)
iow: If you love AUDIO, you qualify (irrespective of anything else, including hearing).
'Music' differs from 'audio' in definition, but many conflate them (semantics).
I'm quite certain: Beethoven was still a MUSICPHILE, though he had gone deaf between his twenties and forties.
*There wasn't much in the way of 'audio', back in Ludwig's day, for him to,"love".
Would he have, "loved" it?
*TOTALLY: non sequitur to the initial thread topic, but: semantic gymnastics are fun!
