I see it that way too, but as you can see here in the forum, there are very different opinions on this. Judges also decide on such disputes always on a case-by-case basis and differently.
For those who think it wouldn't bother them:
Imagine you have a small child who is slowly growing. You planted the first lawn, the son can walk and kicks a few balls with dad in the own garden for the very first time – you make a video of it – and you can hear the neighbor’s droning music in the entire recording. Then there are other afternoons, other "first times," other beautiful family moments you record – but never without country music in the video.
Would that really not bother you?
Tomorrow the little one has a birthday. I would have wished that we could give him his sandbox (the sand is not in yet, it was noisy again today and I cried again instead of working outside)… and I would have wished that we could record a video again in the garden tomorrow. But honestly? I am already afraid of it. So we will probably close the door and celebrate inside. :(
The fact that the neighbor listens to music in the garden, often too, should actually be taken into account when building a new house. If you are overly sensitive to something, you should also consider this when building a new house and buying land.
It won’t be that bad, you wrote it yourself. It only bothers you. The neighbor has made a step in your direction and turned the music down. Now the question is whether it’s your turn to take the next step?
