Who has the best hard rock hit of the 21st Century? That's what we're trying to find out with the Rocktober Rumble tournament, which now enters the second round of voting.

On one side of this match-up, you've got Linkin Park, who handily won their first round pairing as "In The End" bested Chevelle's "The Red" to take the victory. The track was all over the airwaves back in 2001, when the Hybrid Theory album helped put the band on the map. But is it part of the "end" game for "In the End" to get another victory?

We'll see Linkin Park square off against Queens of the Stone Age's "No One Knows," which edged out Alice in Chains' "Check My Brain" in the first round of the Rocktober Rumble. The song, which was nominated for a Best Hard Rock Performance Grammy, is ready to rumble against Linkin Park, so let the battle begin.

You can vote once per hour through the deadline of Friday, Oct. 21 at 10AM ET for either Linkin Park or Queens of the Stone Age, and be sure to return frequently to ensure your favorite song advances. After voting here, be sure to click the red button to vote in the next matchup.
