For no good reason I can explain, I think the vocals would have been better sung up an octave. And a bit more in tune, but I have really no right to criticise! :)
Two out of three people wonder where the other one is.
It's not metal enough for Ozzy. You cant call it metal just cuz your singing about the devil. It's more a cross between the B52's and Flock of Seagulls, with a Styx-like opening. It's catchy. Very '80s. I could see myself getting jiggy with it back in the day. I give it an 82.
(BTW, I got your email and responded back to home instead of work. Will try to catch up with you later today)
