You have my sympathy babaloo - nothing worse than that irritating beat. Can't see why anyone would want to listen to it in the first place but each to their own I suppose. However it doesn't excuse the lack of consideration for neighbours. I have been lucky in 20 years plus living in a flat that I have never had exceptionally noisy neighbours, because it would drive me nuts.
Talking of noise, my flat backs on to the Greystead Road flats though at a distance of perhaps 100 yards or so. Fortunately the distance and my double glazing is just about enough to make bearable the ridiculous level of 'music' that on occasion emerges from there at a late hour, often till 3 or 4 in the morning. This is usually at the weekend (though that doesn't excuse it) but happens even on weekday nights sometimes. God only knows what it must be like for the other residents there - I am surprised murder hasn't occurred!!
I hope you can manage to resolve your situation amicably it, though I wouldn't hold my breath....
