Dark Matter Music

I am not very familiar with this theory of dark matter, but apparently many scientists believe that it is the dominant substance that makes up the universe/space. Well, now some scientists are running experiments on the music that dark matter makes. I think we already knew what dark music sounds like, though. The Prince-lord of Darkness himself (H.I.M., you sly devil, you...) already beat them to it, I say. Come on, science... get with it.
