"Starman" is much better than "Missa Solemnis". Due all my respect to Beethoven.

Your contention would have been more believable if Bowie actually believed the star man he sang about was real. He did not. He did not believe that there was a starman waiting in the sky who told us not to blow it 'Cause he knows it's all worthwhile. Bowie did not believe it's all worthwhile.

(quoted) Once in the world’s history men did believe that the stars were dancing to the tune of their temples, and they danced as men have never danced since. With this old pagan eudaemonism the sage of the Rubaiyat has quite as little to do as he has with any Christian variety. He is no more a Bacchanal than he is a saint. Dionysus and his church was grounded on a serious joie-de-vivre like that of Walt Whitman. Dionysus made wine, not a medicine, but a sacrament. Jesus Christ also made wine, not a medicine, but a sacrament. But Omar Khayyam makes it, not a sacrament, but a medicine. He feasts because life is not joyful; he revels because he is not glad. “Drink,” he says, “for you know not whence you come nor why. Drink, for you know not when you go nor where. Drink, because the stars are cruel and the world as idle as a humming-top. Drink, because there is nothing worth trusting, nothing worth fighting for. Drink, because all things are lapsed in a base equality and an evil peace.” So he stands offering us the cup in his hand. And at the high altar of Christianity stands another figure, in whose hand also is the cup of the vine. “Drink” he says “for the whole world is as red as this wine, with the crimson of the love and wrath of God. Drink, for the trumpets are blowing for battle and this is the stirrup-cup. Drink, for this my blood of the new testament that is shed for you. Drink, for I know of whence you come and why. Drink, for I know of when you go and where.”
