I gave my heart to a simple chord

People worry about kids playing with guns, and teenagers watching violent videos; we are scared that some sort of culture of violence will take them over. Nobody worries about kids listening to thousands - literally thousands - of songs about broken hearts and rejection and pain and misery and loss. The unhappiest people I know, romantically speaking, are the ones who like pop music the most; and I don't know whether pop music had caused this unhappiness, but I know that they've been listening to sad songs longer than they've been living the unhappy lives.
