I myself am willing to go out on a limb and say paper 4 is possibly worth thinking about and not blatant trolling. I presume lukeprog wouldn't have a problem with a paper proposing an fMRI comparison study of atheist/theist Bach listeners. But one would first have to justify such an expense, no? Or at least formulate an hypothesis:

So what is the (appreciative) Christian experience of (great) religious music like? It is plausible to think that the following features are at least characteristic of it: (i) the sung text is taken to convey maximally deep and important truths about existence and the world — including, for example, truths about God, Christ, and the possibility of human salvation — and to convey them in a peculiarly powerful way; (ii) this power is registered, often or usually, in the emotional involvement that such works invite, so that listeners are stirred to feelings of, for example, wonder at the glory of God, gratitude for Christ’s sacrifice, or hope at the prospect of redemption; (iii) ‘emotional and spiritual succour’ is taken in the apprehension of these truths and the stirring of their attendant feelings; and (iv) this succour underwrites a very high valuation of the works which offer it.
