People don’t listen to sad songs to make themselves miserable. When you write a sad song, and sad songs are very popular, be aware the listener is not interested in hearing you whine about your awful predicament.
What a sad song should do is tug at the heartstrings but then show a way out – redemption, hope, light at the end of the tunnel. Make them cry, but then offer a hint of a smile.
A sad song should show how the singer was faced with a sad situation, one the listener can identify with, but in the end found a glimmer of hope, a way forward.
“Don’t despair”, it should say, “I’ve been there and there is hope, I got over it, and so could you.”
