Yowza! We've got a clash of the titans in Round 2 of March Metal Madness. Slayer's "Bloodline" squares off against Pantera's "Revolution Is My Name" on the path to determine the Best Metal Song of the 21st Century.

Slayer took on Cannibal Corpse in Round 1 as "Bloodline" dealt a death blow to "Make Them Suffer," amassing over 75 percent of all the votes. It might not be as easy this time around because Pantera will be out for blood.

Pantera's "Revolution Is My Name" took on modern heavyweights Mastodon's crushing "Blood and Thunder," but it was Mastodon who wound up crushed. Gathering two thirds of the votes, Pantera steamrolled their way to Round 2.

So which song will move on to the Quarterfinals of March Metal Madness 2016? Listen to both tracks and vote for either Slayer's, "Bloodline" or Pantera's "Revolution Is My Name" as the Best Metal Song of the 21st Century in the poll below!

(This poll will end on Tuesday, March 15, at 9AM EST. Fans are able to vote once per hour, so keep coming back to make sure your favorite song wins!)

Slayer, "Bloodline"
