When Alan Freed coined the term "rock and roll" in 1956, he was referring directly to young Americans listening to the popular music of the day whilst fornicating in their automobiles. The term described the motion of said automobiles.
Music, as all of creation, MUST conform to a certain order. When it fails to do so, it is disordered and useless (at best) or harmful (very harmful in some cases) at worst.
And who, pray tell, is the arbiter of what conforms to a certain order? There was a time when one wasn't allowed to use diminished chords when composing music. These chords were reffered to as
diablo in musici, literally meaning, "devil in the music". Well, if you're familiar with classical music, you will know that diminished chords are a mainstay of the composer. Is classical music Satanic, seeing as it contains devilish elements?
