Was wolfgang amadeus last song The Magic Flute?

No, Wolfgang Amadeus Mozart's last song was not The Magic Flute. His final completed composition was the Requiem in D minor, K. 626, which he was working on at the time of his death in 1791. The Magic Flute, K. 620, was composed in 1791 and premiered in September of that year, making it one of Mozart's final operas, but not his last composition.
