My wife and I are currently renting in Brisbane, and our neighbour really, really likes sad music - normally this wouldn't be a problem however he hits the play button at 8AM and it doesn't stop until 8PM or later most days. My wife and I both work from home, and there isn't a room, area of the house or yard where his blaring sadsack music can't be heard.
He's an unreasonable person, and when approached wont wear headphones or lower the volume.
What are our options here? It's getting really close to the petty revenge aspect but we'd much rather he just shut up.
