Slipknot and Drowning Pool both dominated airwaves in the first half of the 2000s with "Duality" and "Bodies" respectively. These two songs have been immortalized and are some of the biggest metal hymns to grace the new millenium. It's a juggernaut fight in Round 1 of March Metal Madness to determine the Best Metal Song of the 21st Century, but only one will make it to the second round.

Slipknot's "Duality" comes off the Rick Rubin-produced disc Vol. 3: (The Subliminal Verses) and helped bolster the band's already rising status. The song features the full gamut of Corey Taylor's vocal abilities, switching from deranged and ferocious barks to clean refrains with ease. His singing takes the lead role here and the spoken word verses help the seesaw-like energy.

"Bodies" is one of the biggest anthems to emerge in the 21st century and will be a tough song for Slipknot to beat. The Drowning Pool hit features wah pedal and pick scrapes texturing the song along with the stunted chugging in tandem with the unforgettable lyrics sung by late frontman Dave Williams. Anger personified, "Bodies" is a strong contender in this tournament, but has to get past Slipknot's "Duality" to advance to the next round.

So which song will move on to Round 2 of March Metal Madness 2016? Listen to both tracks and vote for either Slipknot's "Duality" or Drowning Pool's "Bodies" 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!)
