Oh hey I just thought of something else you could do.
Print some "Black Water" materials off from your computer and leave them laying around on your desk and occasionally drop one in front of him and ask him to get it for you.
When he sees "Black Water" you start talking about how bad these guys are and their reputation they developed around the world.
When he asked what you are doing with them. Simply state you have a problem with a neighbor that sings too loud, and are looking for a cure.
