WIY: I think that’s patently ridiculous. Does eating a recipe made by a spiritually negative person have a negative impact on you?
And even if you’re right (which I’m not agreeing to in the slightest), you need to prove that it’s the composer that matters. Maybe it’s just the person playing it. Which isn’t Shayach to a recording. You need to bring a Makor for your general concept and that this spiritual P’gam stays in the composition forever.
