Hell Is That Noise: The title track of "Riding a Black Unicorn Down the Side of an Erupting Volcano While Drinking from a Chalice Filled with the Laughter of Small Children" begins with some loud call of an unidentified animal (a unicorn?), almost like a really loud, drawn out 'moo' from a cow.
Actually, it's a horn blow. At least, how some might hear it as.
Misattributed Song: A lot of people think Voltaire made the song "If I Only Were a Goth", but the song was actually recorded by the band ThouShaltNot. Granted, the singer does sound similar.
