6. “Over The Rainbow” from The Wizard Of Oz (1939)

We all dream of that place somewhere over the rainbow where we could just freely and happily be ourselves as we live our lives in a world free of violence. Then again, its the very challenges life presents that makes it really worth living as it makes us stronger people the moment we overcome them. But also, there’s nothing wrong with thinking about the dreams that you dream of once in a lullaby. The song has been included in the National Recording Registry by the U.S. Library of Congress for its “cultural, artistic and historical importance to American society and the nation’s audio heritage”.
