Are you a glass-half-full or glass-half-empty sort of person? The answer to that question may help determine your vote in our latest Clash of the Titans, which pits Judas Priest's 'Beginning of the End' against Black Sabbath's 'End of the Beginning.'

As fans of both bands are aware, this matchup takes advantage of not just a coincidence of titles, but one of timing: both songs are available on the groups' most recent albums, with 'End of the Beginning' appearing on Sabbath's '13,' which reunited original singer Ozzy Osbourne with bandmates Tony Iommi and Geezer Butler for their first full-length LP together in 35 years. 'Beginning of the End,' meanwhile, can be heard on the new Judas Priest record 'Redeemer of Souls,' released July 8.

"Talk about coincidence," Priest singer Rob Halford nodded when Loudwire asked about the similarities between the song titles (embedded below). "We had that song before the Sabs had finished that record. You just throw your hands up ... It's the same, but it's different."

That being said, Halford has been around the block enough times to know it isn't worth getting too upset about -- or tossing out a perfectly good song over. "We grew up together, so we feel that ... I'm sure that Tony, Geezer, and Ozzy will see the humor in that," he added. "You bump into each other occasionally."

So which 'End' gets your vote in this Clash of the Titans matchup? Check them both out below, and remember: you can cast a ballot once an hour between now and when voting ends on Sunday, Aug. 17 at 11:59PM.
