It's so loud where i live anyway with the road, shops, pub etc that it's ok for playing tunes at a decent volume but I don't play too loud or too late at night as there are popel next door and below me. In fact my newish neighbours play fast bangin' cheese trance which I really dislike myself at all hours and they have been pissing all the neighbours off including me by playing it at silly hours all the time.
I'ma reasonable man and don't mind in the day/evening or sometimes if they have a party but most nights all nights and onwards into the morning so loud, especially as i gotta get up for work,a and so's everyone else in the buildings. I been woken by them and i'm 2 floors above them. The people next door aint happy and there's kids about and stuff so pretty inconsiderate I reckon. Not saying they shouldn't play it but maybe keep it down a bit at night?
It's interesting though cos I play pounding tunes but not with complete disregard for my neighbours, and in my younger years not working i pissed the neighbours off a few times....so what goes round comes around!

Respect thy neighbour ;)
