Alice Cooper's signature anthem goes up against a chapter from Rush's career-spanning trilogy in a heavyweight fight from our Rock’s Scariest Song competition.

In honor of Halloween, we’ve chosen 16 of rock’s scariest songs. The field will be sliced, diced and chopped in half every week based on your votes, until only the scariest song in rock history remains alive.

In this round, we're pitting the Cooper classic "Welcome to My Nightmare" against Rush's "Witch Hunt" — and while both songs have made quick work of their opponents in previous rounds, only one of them is moving on from here. Cooper's "Nightmare," the title track to his hugely popular 1975 album, recently dispatched Judas Priest's "The Ripper," while "Witch Hunt," which served as the chronological start of Rush's "Fear" song series, easily defeated Iron Maiden's "Fear of the Dark."

So which one of these songs will emerge victorious from this round? 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. 26 at 11:59PM ET. Your choice for Rock’s Scariest Song of all time will be revealed on Nov. 1, 2015.
