As somebody who enjoys music every day, attends live performances, and keeps up to date with some music blogs. I think it's an over assessment to call music the most valuable contribution our species makes to the universe. Nevermind the fact that we have no clue what our contribution is at all in the universe. Music is good, it's shaped societies, and the like, but so have many other things, and I don't think our species would've died off without music. TBH I think most people would barely notice after a little bit if music just disappeared.
