The most wonderful time of year... with neighbors singing xmas lights

Hi guys thanks for all the suggestions! I knew that talking to them was probably the right thing to do but I felt badly because the music at night was actually not the problem, I can sleep through almost anything, but it was a major problem during the daytime when I was trying to study. Differential calculus does not get any more jolly with "jingle bells" playing nonstop! So I would have had to ask them to turn it off completely and not just at night, which I thought would be kind of grinchy because they have young kids

Anyway this is all in past tense because I think one of my other neighbors yelled at them? The singing has stopped completely for over a day!
