Live in terraced housing and neighbours are playing music really loudly - earplugs are not doing anything to block it out. Wasn't told of any party happening and they don't seem to have people round - so it's not a party or special occasion as far as I'm guessing. I'd understand if it was a Friday or Saturday night but it's now 1am on a (technically) Monday morning when everyone has work. AIBU to go and knock on their door and ask them to turn it down considerably?!
