Get a super loud stereo, mount a set of sub woofers on your ceiling. Find the bassist hip hop song you can find. Every time you leave the house play it loud with the bass on high.

If any other neighbor complains, tell them it's the guy upstairs.

When he complains, tell him it's time to make a deal. You will stop the Hip hop, if he ceases his crap to.

If that don't work, go stay at a friends house for a few days, leave the stereo on the whole time. Show him that you can make more noise, for longer.


Other wise call the cops.
