10 Heaviest Metallica Songs

Throughout their catalog, Metallica have always been a band that wrote about the atrocities of war. From the Hellscape on the battlefield to the after-effects of servicemen and women suffering from PTSD, the scenario seems to have a great fit when set up against Metallica's wall of guitars.

In "Disposable Heroes," the band wrote one of their boldest condemnations of war, detailing a soldier's evolution from an impressionable kid to an almost mechanical killing machine who has nothing except his firearm to turn to for comfort. The verses are pretty straightforward, except for the breakneck tempo that would leave any rhythm guitarist with a sprained wrist. When detailing the more horrific passages of the man's life, the riff changes from a typical metal stomp to one of the fastest guitar punches on a Metallica record. It's almost as if the choruses are giving the listener the sensation of being right next to an AK47 as its blowing away a group of soldiers.

Just when you feel like you can't go any higher in intensity, James Hetfield's scream of "I was born for dying" takes the song to the next level before raging its way to the end. "Disposable Heroes" is one of Metallica's most savage moments with a sound that can still be felt in modern metal bands.
