what a lot of people dont realize, is that the title track is actually about alcohol addiction/abuse, or really any kind of addiction (but alcohol specifically, given james hetfields history with the stuff). the opening song battery, while being an amazing example of speed metal prowess (as well as having an amazing opening) is about someone with a psychological problem commiting battery on people. the only song on this album that has any swearing in it is damage inc. almost all the songs on the album are about not being in control of ones own life, be it due to addiction, war, insanity, rage and what have you. while its not the greatest speed metal album in existance (that goes to battalions of fear by blind guardian) in my opinion it certainly takes the title for 80s thrash.
