Just curious why you explicitly "hope there is no cure"? Seems like an odd wish. If music has little to no effect on you now, why would you even care? Furthermore if a "cure" did exist, what would be the downside of trying it?
If you were enjoying it then how would it differ from any of the other variety of things you already enjoy that you spend money on?
How is that different than letting reflections of light off of objects control your emotional state? Do you also have no emotional reaction to art, or even as simple as preferring a certain color?
Would painting a room bright pink be no different to you than painting it black? Does looking at roadkill or a corpse feel absolutely no different to you than viewing something most would consider calming like a sunset, flowers or someone who you consider to be beautiful? If you do feel different, then yes, light reflecting off of objects does create an emotional reaction to you.
