This. 10:30 am would not be considered a problem legally where I’m from, you can only make a noise complaint before 7am and after 11pm. People are allowed to enjoy their lives, having neighbours play music during the day is just part of living near other humans.
Do not take petty revenge because that probably is illegal. Be an adult and deal with it.
I have been diagnosed with aphantasia, so I’m a 5. I have no ability to visualise anything in my head, I was in my 40s before I realised that “minds eye” is not a metaphor for most people.
