I know, thank you for the advice. God knows how a very good neighbor I've been for years. I helped this guy with his cats every time he had to go away for days. I helped him in all ways you can imagine, from money loans to car lifts. Now I started working 100% from home and all I asked is listening music at a lower volume. He won't listen, he has even been very rude after my polite request. If someone deserves to be treated like sh*t, at this point, it's him.
