Nine Inch Nails [SEP] Music and lyrics
Nine Inch Nails has been described as incorporating alternative rock, industrial rock, industrial dance, industrial, electro-industrial, industrial metal, electronic rock, and alternative metal. AllMusic's Steve Huey states that "Nine Inch Nails were the most popular industrial group ever and were largely responsible for bringing the music to a mass audience". Reznor has never referred to his own work as industrial music, but admits to borrowing techniques from such early industrial bands as Throbbing Gristle and Test Dept. Despite the disparity between those artists initially operating under the term "industrial" and Nine Inch Nails, it has become common in journalistic descriptions of Reznor's body of work to describe it as such.
