From my standing, industrial covers some of my favourite bands.
I'll always see NIN as industrial, i'm afraid. The same goes for Rammstein, Static-X, even Marilyn Manson.
I'd say that NIN has moved away from the industrial scene since 'The Downward Spiral', as 'The Fragile' seems to focus more on guitars than synths. However, the next album is reported to return to the more electronic feel of previous albums, so maybe you'll change your opinion :) After all, KMFDM are big fans of, and are influenced by, NIN.
Well, let me elaborate:
Nine Inch Nails is one of those bands that defies all genres.
Nine Inch Nails' first album "Pretty Hate Machine" was synth-pop with a "bite". (I still love "Head Like a Hole" and "Sin"). The album is kinda weird because it sounds like it belongs both to the 80's and the 90's.
Nine Inch Nails' second album "Broken" was the most "industrial" of them all. It belongs to a genre known as "industrial rock". (A genre some people say only exists so we have a place to put NIN). I would, however, dare to say that this album is more rock than industrial. But yet the bonus track ("Suck") is true industrial.
Nine Inch Nails' third album the legendary "Downward Spiral" are in my opinion impossible to label as being any genre. Here a few industrialesque elements synthesise with weird electronic funk draped in guitars that, though they are horribly distorted, are nothing like metal.
With "The Fragile" Nine Inch Nails finally proved that they were not industrial at all, making a record that critics have described as being closest to Pink Floyd.
For a clarification of what the industrial genre (and it's subgenres) is I would recommend anyone interested to pay Industrial.org a visit. They have some excellent faq's that will answer most of your questions.
The site also caters for the musician with their Gear Fetish pages as well as some really beefy faq's.
Now, let's get on with the Linkin Park flame thread, shall we?
I am, therefore I suck.
