They say you should never watch laws or sausages being made, if you want to respect the result. The boy[*] next door is a wannabe DJ inflicting his practice on his neighbours, and I think the same may be true of club music
Or of course he might just not be very good. Were I in his position I'd be using some kind of small monitor speakers and not an entire fricking PA system
Oh, I left a dangling footnote. I say "boy", but biologically he appears to be a full grown adult. I guess with some people the theory of mind comes later
