Remember when #CarminaBurana was the universal dramatic music? It was everywhere, in trailers and movies, whenever something super dramatic was supposed to be happening.

Or #HallOfTheMountanKing, remember that one? It used to play whenever quirky and weird machinations were afoot.

Or #Powerhouse! That plays whenever a deranged and complicated contraption is operating! (This one was heavily associated to Looney Tunes.)

I don't think we use these universal public domain motifs as much anymore.
