Cover art for With Teeth lyrics by Nine Inch Nails

to me this song is describing something, such as a relationship or a drug that has such a power that it just rips through your soul and changes you. the lines are basically like what you were and believed before (like a barcode) but then this "thing" comes along and the lines blur and change they are no longer the same and you are different

the title then refers to that the album has that same driving effect and power
