14. Wolfgang Amadeus Mozart - O zittre nicht, mein lieber Sohn
This aria from Mozart's The Magic Flute is The Queen Of The Night's first. While it's not as well known as the other big aria for that character, "Der Hölle Rache kocht in meinem Herzen", it is a comforting song from mother to son that translates as "Tremble not, my dear son / You are innocent, wise, pious."
