"Before I Forget" borrows elements from a much older Slipknot song "Carve", recorded before their self-titled album. The earliest version was in 1996 with Anders Colsefni on vocals. "Carve" was for the SR Demo 1997, referred to by fans as Crowz.
"It's about standing your ground and deciding to be a good person, no matter what people say," recalled singer Corey Taylor. "[Producer]Rick Rubin was convinced the chorus wouldn't work. I told him he was crazy. Lo and behold, it's one of our biggest songs and we won a Grammy for it."
The last 18 seconds of the full-length song feature morse code in the left channel spelling "Slipknot", and Taylor muttering, "You're wasting it", reversed.
