Unless you are a melophobe, you most definitely have a favorite song.
So, pick your favorite song of all time—assuming it tells a story—and write that story that you feel is behind it. Make sure to emphasize the hidden message, if there is one.
But don’t make the song too obvious, for I, hopefully along with fellow readers, will try to guess the song that is being used for inspiration and post it into the comments.
Good luck and have fun!
