I am renting in a council house. Sometimes my neighbors right below me play loud music and when it’s past 11pm or 12am I go down and ask them to turn it off

Recently some other neighbors not in immediate proximity started doing the same pretty often, and sometimes closer to 1am. I can hear it very well either way. Why their immediate neighbours do not confront them? Seems majority are pretty adequate people in the house

If I do it am I an asshole, or get seven years of bad luck by UK standards?
