Rammstein are heavy on their stage show, but they won't be able to use their flamethrowers in this competition. The Germans and their anthem "Feuer Frei!" are up against one of America's biggest acts of the millennium in Lamb of God and their fan-favorite "Laid to Rest." Only one will advance to the next round as we determine the Best Metal Song of the 21st Century in this year's March Metal Madness tournament.

Bang! Bang! That's what "Feuer Frei!" is hoping to do to "Laid to Rest." The industrial powerhouse that is Rammstein continued the success they built up after Sehnsucht and committed another hit to their legacy. The song was featured in the action film xXx and received a significant amount of attention stateside from their appearance in the movie's opening scene.

"Laid to Rest" kicks off Lamb of God's third album, the stellar Ashes of the Wake, kicking up more dust with every riff. Singer Randy Blythe sees red throughout the whole track, screaming in a fit of rage with unmatched intensity. The band employs a balance between melody and slugging rhythm work and can overtake Rammstein with enough votes.

So which song will move on to the second round of March Metal Madness 2016? Listen to both tracks and vote for either Rammstein's "Feuer Frei! or Lamb of God's "Laid to Rest" as the Best Metal Song of the 21st Century in the poll below!

(This poll will end on Tuesday, March 8, at 9AM ET. Fans are able to vote once per hour, so keep coming back to make sure your favorite song wins!)

Rammstein, "Feuer Frei!"

Lamb of God, "Laid to Rest"
