The old me would crank it up to show him what loud really was! But now, I would try to talk to him about it, explaining that you have lived there for several years, never had a problem... invite him over to have a beer or something... like a welcome to the building, sorry about the noise kind of a thing. If you make friends with him, or try to, he is way less likely to call the cops, or management, or even complain at all. If he did complain, he would probably be more inclined to knock on your door and himself if he knew you... If all that doesn't work you could start shoving foam earplugs under his door...
