Never considered that. I’ll play her some Ozzy some time and see what she does.
Certain bands insert white noise frequencies into songs that elicit certain feelings. These are subharmonic and inaudible but a sensitive person will pick up on them. Additionally they “excite” the song too. THis involves amplifying a few frequncies just above the human hearing range and it tickles your ears. Its very subtle but being Im a home recording enthusiast, I can tell when they do this. Its why crap songs like Beyonce sound pleasing yet when you break it down , the song is simple junk .
