"Motorbreath" is about "living life in the fast lane" and "not ending up like others [the] same song and dance." It means to live life to the fullest and enjoy being alive. During early shows former lead guitarist, Mustaine, said that it was their version of a love song. This is the only song in the history of the band that is credited to Hetfield alone, one of two in which Ulrich doesn't have a credit (both on this album, the other is "(Anesthesia) Pulling Teeth"). .
