While acknowledging the power of music in the original Space War I, Macross 7 introduces a new concept of Song Energy. In the original Super Dimension Fortress Macross, Lynn Minmay's music was a way of bringing culture to the Zentradis, causing similar effects when exposing the Zentradis to acts of kissing and human intimacy. However, Macross 7 expands and builds the concept of Song Energy on the already established fact of music's effectiveness in the last war.
