Industrial Music is a term that derives from the 1970s Industrial Records label. Today however, there is hardly any resemblence between music on that label and what is known as Industrial Music. "Industrial" is a term which mostly came to represent the "other" music that wasn't pop, punk, metal or electronic.
Bands latched onto the non-musical messages of Industrial and it just stuck. Despite this, many bands hate being called Industrial because it means nothing specific. If you wear black or have boots or use experimental electronic sounds or something as superficial, you are Industrial. This has basically been the way it's been since the 1980s.
If we want to refer to a genre by its label, then we have been listening to Metropolis Records music since the 1990s. Maybe one could say Wax-Trax music or something similar in the USA.
Whatever the case, why call it "Industrial" anymore? What about the information war and other topics the original movement was about are still even relevant in the music? It's basically evolved into a dance genre, which is why I specify the music here as "Industrial Dance".
I don't think the name will change but it's not really appropriate anymore. The same is true with other genres but oh well.
