We've got an incredible March Metal Madness matchup in Round 2 as two legendary metal heavyweights show they've still got it! Metallica's "My Apocalypse" will face off against Judas Priest's "Valhalla" on the road to crown the Best Metal Song of the 21st Century.

Thrash kings Metallica took on the Swedish vikings in Amon Amarth in Round 1 in what was a fierce competition. Amon Amarth fans came out in full support of "Twilight of the Thunder God," but "My Apocalypse" overtook the song and sent the vikings to the golden halls of Valhalla. Speaking of Valhalla...

Judas Priest's "Halls of Valhalla" kicked the legs out from under Megadeth and "Kick the Chair" in Round 1. The Metal Gods amassed nearly 60 percent of the votes and are now up against another Big 4 act in the form of the mighty Metallica.

So which song will move on to Quarterfinals of March Metal Madness 2016? Listen to both tracks and vote for either Metallica's "My Apocalypse" or Judas Priest's "Halls of Valhalla" as the Best Metal Song of the 21st Century in the poll below!
