Hello,
I do not live that street but I have a big sympathy to you. I have been annoyed by a neighbour coming back late nights often and using showers and washing machines or talking and watching TV loudly till late. Recently they installed something vibrating continuously which I complained, and complained to council also.
I would recommend to go to council straight away, especially if music, there is no excuse of domestic noise. However if it happens at night the council noise team would not go there, you just need to give some records as evidence, and they do write a letter to the household. Hope your other neighbours are complaining also.
Noise nuisance can be draining, hope it will be sorted out soon.
