What are you talking about? The Pefect Drug single had awesome remixes of that song, especially Plug (Luke Vibert's) mix. Most of those is what Industrial should sound like. By the way, Pretty Hate Machine represents EBM (Electronic Body Music). A sub-genre in the Industrial spectrum. It represented Industrial Dance...loosely connected to Synthpop, also credited for the creation of Goa/Psy. Popular during the middle 80s.
Fixed gets credit since J.G. Thrilwell (name sound familar? He composes the music for Venture Bros) of Foetus and Peter Christopherson of Coil remixed those songs. Two lifeblood artists of the genre. Technically, thats what Industrial is. Abrasive, hard as fuck, little tone/melody music.
