Remember when Judas Priest was putting backwards messages in songs to make kids kill themselves? Never mind that it would never work because your brain doesn't go around playing songs backwards and as Ozzy Osbourne once said, why would you want to kill off your revenue source. Well now you can go listen to those evil songs backwards, as they were (apparently) intended! Note that Nature Trail to Hell might be the only one that's for real.
I always got a kick out of people pointing to evilness in music because they would use like Skid Row and Cheap Trick while meanwhile Deicide and Morbid Angel and Incantation are much more obvious. Those outrage committees obviously weren't looking very hard. Hat tip VorJack at Unreasonable Faith.
Below: Rob Halford, lead singer of Judas Priest. Apparently he has admitted that "Breakin' the Law" when played backwards has the following subliminal lyrics: "British male seeking SWM 18-23 years old with kind of tousled sandy blonde hair and washboard abs for friendship & maybe more. I enjoy hiking, Italian wine and long walks on the beach. No games please."
