We're down to the final four of March Metal Madness 2016,  and it's Iron Maiden representing the Headbanger Region against Disturbed coming out of the Stage Dive Region. The winner will advance to the Final Round as we crown the Best Metal Song of the 21st Century!

Iron Maiden have been on a warpath with "The Wicker Man" defeating Dream Theater's "On the Backs of Angels," Tool's "Schism" and most recently taking nearly 59 percent of the votes over Black Sabbath's "God Is Dead?" The streak looks impressive, but Disturbed have been on a tear of their own.

"Down With the Sickness" from Disturbed has taken down some challenging opponents, having knocked off Ghost's "Cirice" which was fresh off a Grammy victory, Anthrax's "The Devil You Know" and in the Quarterfinals, overtaking Slipknot's "Duality" with 52 percent of the votes.

So which song will move on to the Final Round of March Metal Madness 2016? Listen to both tracks and vote for either Iron Maiden's "The Wicker Man" or Disturbed's "Down With the Sickness" as the Best Metal Song of the 21st Century in the poll below!

(This poll will end on Tuesday, March 29, at 9AM ET. Fans are able to vote once per hour, so keep coming back to make sure your favorite song wins!)
