An answer song (sometimes called a response song) is a song made responding to a previous artist’s song. Usually as a defense or indictment of the song it is responding to. A famous example is Lynyrd Skynyrd’s “Sweet Home Alabama,” which was in direct response to the Neil Young’s searing portrait of the south in his song “Alabama”. Or Woody Guthrie’s “This Land of Your Land” as a response to Irving Berlin’s “God Bless America”.
Although your answer song does not need to respond to a song. Feel free to write a song in response to a newspaper headline, a bumper sticker, or a piece of junk mail. Get creative.
