If you can't get enough melody in your metal, this is the matchup for you! Avenged Sevenfold's "Nightmare" is taking on Children of Bodom's "Everytime I Die" in Round 1 of March Metal Madness. The two giants will be looking to advance to the next round of the Devil Horn Region in the quest to determine the Best Metal Song of the 21st Century.

Avenged Sevenfold soldiered on after the loss of their drummer Jimmy 'The Rev' Sullivan, tapping Mike Portnoy to fill the void on Nightmare. The title track is one of many standouts on the disc and volleys between searing melodic leads and stomping rhythms as M. Shadows takes the listener through his impactful lyrics dealing with inner struggle and how it translates to every day life.

Follow the Reaper was one of the most impressive albums to come out of the new millennium and was released when Children of Bodom mainman Alexi Laiho was just 21 years old. The album features lightning fretwork from top to bottom as the Fins redefined melody in extreme metal. "Everytime I Die" is one of the more cinematic songs off the album, featuring simpler yet powerful lead work and demonstrates the band's ability to switch gears without sacrificing quality.

So which song will move on to the second round of March Metal Madness 2016? Listen to both tracks and vote for either Avenged Sevenfold's "Nightmare" or Children of Bodom's "Everytime I Die" as the Best Metal Song of the 21st Century in the poll below!
