i find playing snuff porn really loud works really well too in shutting the neighbours up too........especially if you're filming it live......
that or sacrifice a live chicken (none of that Maple Leaf crap) infront of their door and writing "death to hip hop" in the chicken's blood.......not only will they stop broadcasting, it'll also give them good reason to move out as quickly as possible.....keep repeating until you eventually find neighbours that u can tolerate....works like a charm....
