Answering both questions 1.) The last time I heard music at Mass that reinforced my faith was back some time in January before the Bishop diallowed singing. 2.) I've never heard the cosmos in my parish nor do I expect to. a.) The cosmos isn't a sentient being so it can't choose to attend Mass, much less eventually convert to Catholicism. b.) Given its size, it's impossible for the cosmos to fit into the church of my parish, even if it was sentient and did take an interest in attending Mass.
