Had 2 neighbors next door house and one time bottom floor of our apt.. both played music and when we politely knocked on their door to ask them keep it down because we had to sleep at 3 am weekday mornings, they keep it down for an hour. Then it would happen again and again and again.. It got to a point they would deny (dumb fucks) there was anything on.
Found out both were meth addicts and sometimes it would go on for days - 7 days straight...
Cops finally got involved.... One got arrested the other was kicked out....

Karmic Payback is a bitch....
