A few days ago I quoted
George Weigel on the new pope:
Benedict XVI is a Mozart man, who knows that Mozart is what the angels play when they perform for the sheer joy of it.
I have since happened across a similar remark by Protestant theologian Karl Barth, quoted in his New York Times obituary:
Whether the angels play only Bach praising God I am not quite sure; I am sure, however, that en famille they play Mozart.
