 Backmasking is often used for aesthetics , i.e. , to enhance the meaning or sound of a track . During the Judas Priest subliminal message trial , lead singer Rob Halford admitted to recording the words " In the dead of the night , love bites " backwards into the track " Love Bites " , from the 1984 album Defenders of the Faith . Asked why he recorded the message , Halford stated that " When you 're composing songs , you 're always looking for new ideas , new sounds . " Stanley Kubrick used " Masked Ball " , an adaptation by Jocelyn Pook of her earlier work " Backwards Priests " ( from the album Flood ) featuring reversed Romanian chanting , as the background music for the masquerade ball scene in Eyes Wide Shut . At the end of " Before I Forget " by Slipknot , lead singer Corey Taylor 's voice can be heard saying " ... You 're wasting it " which is in reference to how Rick Rubin , the producer of their album Vol . 3 : The Subliminal Verses , wanted Taylor to change the chorus vocal melody because he felt it wasn 't catchy ; however , Taylor stood his ground and the chorus stayed unchanged .
