..Well, music can affect different sparks in different people, but I don't think it would affect anything inanimate... You're talking about the energy of sound, coming from a digital device, say perhaps. Sound can spark different emotions and reactions, thus probably sparking YOUR personal energy.
Depending on the person, what they're feeling at the moment, who knows. You singing could raise there energy to a different kind of emotion or level. You could stir the negative energy into positive. It all just depends.
I know whenever Flagg and I transfer energy to each other, our energy interacts sort of like a blood transfusion. It mixes, and makes us both feel what the other does, trading one emotion/vibe for another, thus helping each other feel much better.
Just assume that depending on your bond with the person, of course singing could help them. But if you want to not be looked at weird if you're a hoarse singer, I think an energy transfer would work out better.
I guess i'm still a little confused on what you're trying to say, so tell me if i'm getting it or not.
