AFI came so close to entering the Loudwire Cage Match Hall of Fame, but Avenged Sevenfold prevented them from earning their fifth straight victory. Now, A7X and their single 'Hail to the King' are looking to start a run of their own. But they'll have to battle heavy metal royalty in this Cage Match.

We've been waiting for some solid competition to get Black Sabbath into our Cage Match, and A7X may be the band that's up to the task. Sabbath landed at No. 1 on the charts with their recent album '13,' which features the epic single 'God Is Dead?' You can catch the heavy metal godfathers on their North American summer tour. See the dates here.

So, will Avenged Sevenfold reign in this Cage Match? Or will Black Sabbath show them who the real kings of heavy metal are? Listen to both tracks and vote for your favorite in the poll below.

(This Cage Match will run until Monday, Aug. 5, at 8AM ET. Fans can vote once per hour! So come back and vote often to make sure your favorite song wins!)

Avenged Sevenfold, 'Hail to the King'

Black Sabbath, 'God Is Dead?'

Rules of Cage Match:
Fans can vote once per hour for their favorite song. If a song remains the reigning champ for five straight cage matches, it is retired to the Loudwire Cage Match Hall of Fame. With so many great songs out there, we have to give other bands a chance!
