Round 1 of the March Metal Madness tournament is in the books! We started with 32 tracks all vying to be crowned the Best Metal Song of the 21st Century and after thousands and thousands of votes we're down to 16 songs. Round 2 is now under way and there's some great matchups ahead as the competition only gets fiercer from here. Some bands had an easy time in the first round, but they can't rest on their laurels or else they might find themselves sitting by the curb when the Quarterfinals roll around next week.

There's healthy competition among all the regions: Headbanger, Stage Dive, Devil Horn and Mosh Pit. Bands like Slipknot, Iron Maiden, System of a Down, Tool, Five Finger Death Punch, Slayer and a bunch more still on the board, so vote early and vote often! Remember, you can vote once per hour every hour until the polls close on Tues., March 15 at 9AM ET to make sure your favorite song wins and has a chance to be named Best Metal Song of the 21st Century!
