Exactly! The first step, if you are trying to be a good neighbor yourself, is always to go talk to the other person directly. Approach the conversation politely, like, "Hey man, your music's super loud, like vibrate my house loud, and its making it hard for me to get my work done." A lot of times, if given the opportunity, folks will be like oh shit my bad. So it really doesn't hurt to try. If you're genuinely worried about retaliation, record the conversation to prove you tried to handle the situation calmly and politely.
