If you lowered a microphone onto the Earth's globe you would hear all sorts of noises imaginable. Each place contributing its own sound to the already jarring discord. So many voices, so many instruments, so many styles, all very different yet similar, unique yet common.
If you listen hard enough you will hear music. If you listen even harder you can make out a variety of songs with a discrete combination of lyrics but an overlapping meaning all the same.
If you pay attention to it you should be able to hear the cries of humanity.
