WIY: There is a very, very big difference between concepts brought out of Halachah and other Divrei Chazal and something that is made up. If you show me a Makor in Chazal, I’ll acquiesce. If you can’t, then whatever made-up idea this is is not part of the Mesorah. (I agree with your overall point about music and what is can lead to and those studies are very compelling. One should avoid music that causes them to be inclined in even the slightest wrong way. I completely agree. I’m just disagreeing with this (as far as I can tell) made-up notion of the composer putting his soul into the music and the listener absorbing it nonsense.)
