Judas Priest's "The Ripper" takes on Alice Cooper's "Welcome to My Nightmare" in a particularly nasty second round battle from our Rock's Scariest Song competition.

To celebrate Halloween, we chose 16 of rock’s scariest songs. The field has already been sliced in half, and will be further diced and chopped every week based on your votes, until only the scariest song in rock history remains alive.

Obviously, you could fill an entire bracket just with creepy tracks by either of these legendary acts. But judging from the round one results, it would seem we picked strong, battle-worthy titles in each case. Judas Priest's "The Ripper" – which appeared on the band's Sad Wings of Destiny album – pulled the legs off the Who's "Boris the Spider" by a two-to-one margin. Meanwhile, Cooper buried the mighty Black Sabbath's self-titled, first-album-opening anthem of doom in a much closer fight.

So who gets to live another day? It's your choice. You can listen to both songs below, and vote once per hour in each of the four second round Rock’s Scariest Song battles until polls close on Oct. 19 at 11:59PM ET. Your choice for Rock’s Scariest Song of all time will be revealed on Nov. 1, 2015.
