A person who believes one music genre is superior to all other music genres. Usually has a narrow minded view of expanding upon their music tastes. A parasite to the jukebox in a bar when they put in $5 and play only gutter punk, only metalcore, or only reggae.
Leslie: God, another song from Atreyu? This is like the fifth one!
Mike: Yeah, some audiocentrist put his life savings into the jukebox earlier in the night. I'm tired of this shit.
