The Holy Father's favorite composer is Mozart, another indication of his true insight into the sublimely logical and beautiful. Mozart, I believe, more than Bach, reflects how Benedict's own mind works, in a exquisitely intricate way that leads to the light, but without pretentiousness or drama.
Mozart was far more complete a composer. He's also a lot more fun to sing - I would imagine play, too.
And not all of Mozart is exquisitely intricate. Some of it is really mood setting and there are whole parts of the operas that are downright racy.
