Ive nevered had a problem with my neighbours, once lived in china town and i would party outside every other night the kids in the hood would just dance to the music, cops drove by and never gave a shit, and everywhere i moved since never had a problem, thou all it would take would be a knock on my door and someone ask to politly turn it down, a broom at my ceiling, i would laugh at you and turn it up to a point where i couldnt hear the banging.
