At Mass on Sunday at Corpus Christi Church in Celebration, FL, everything was sung except the Eucharistic Prayer (or so it seemed). None of the "music" was written before 1978. And as in most churches nowadays, once the priest left the altar a chat session began. I do not think this is the type of music referred to below.
C.S. Lewis covers this in The Screwtape Letters, as Demon Screwtape writes:
Music and silence–how I detest them both! How thankful we should be that ever since our Father entered Hell–though longer ago than humans, reckoning in light years, could express–no square inch of infernal space and no moment of infernal time has been surrendered to either of those abominable forces, but all has been occupied by Noise–Noise, the grand dynamism, the audible expression of all that is exultant, ruthless, and virile–Noise which alone defends us from silly qualms, despairing scruples, and impossible desires. We will make the whole universe a noise in the end. We have already made great strides in this direction as regards the Earth. The melodies and silences of Heaven will be shouted down in the end. But I admit we are not yet loud enough, or anything like it. Research is in progress.
