Roy Orbison

David Lynch uses Roy Orbison songs in his movie.  I just realized the reason he does this.  Mulholland Dr has the Spanish version of Crying and the make-up guy in Blue Velvet sings In Dreams.  Roy Orbison bases most of his songs on heartbreak.  Heartbreak must have the precedence of love.  This relationship of total happiness with total sadness reveals the connection between the two people.  In most of his films, David Lynch has an interest in the juxtaposition of two opposite emotions.
