A striking similarity in the structural composition of two pieces of music from completely different sources leaves one wondering could it be that this was by design.
Years ago as a local guitarist I noticed that the Slayer song, "South of Heaven" was quite like the theme song of Inspector Gadget... with the diminished intervals that chromatically alternate downward with the staccato feel and timing. My friend who played the drums and I did a little cover of it where we played both pieces and combined them.
To this day I have never heard anywhere else that there was a correlation or that anyone else had noticed. It was not on the internet - several years ago. So, is it more likely by design or by coincidence that these two songs seem so significantly similar?
