If music is a universal language capable of making people animals and plants "feel" things, I think it would work best with clear notes that can be easily distinguished... like that in classical music or something... or even just a simple pattern of repeating tones in common 4/4 time. I listen to a lot of death metal, but if you don't have an ear for it a lot of it just sounds like distortion and blast beats. Probably hard for plants and simple life forms (no traditional brain) to vibe on.
