The Rocktober Rumble moves on to Round 2 as we attempt to crown the best hard rock hit of the 21st Century. Let's get to the next matchup.

Thirty Seconds to Mars killed it with "The Kill (Bury Me)" in the first round of the Rocktober Rumble, ousting Evanescence's "Bring Me to Life" in a close battle. The melodic rocker was the band's breakthrough single that helped put them on the map, but will they "bury" their next opponent as well?

Green Day's "Boulevard of Broken Dreams" broke the dreams of Rise Against's "Ready to Fall" in Round 1 and the track is looking to pave its way to another victory in Round 2. This former chart-topper spent 14 weeks at No. 1 back in 2004, but will Green Day top Thirty Second to Mars in Round 2?

So now it's time for you to vote. Listen to Thirty Seconds to Mars' "The Kill (Bury Me)" and Green Day's "Boulevard of Broken Dreams" in the players below, then make your vote. You can vote once per hour through the deadline of Friday, Oct. 21 at 10AM ET. And to vote in the next matchup, click the red button after you've cast your vote to see the next pairing.
