Noisy opera music

HAHA I'm not sure if this is coincidence or not but YESSS, I'm so glad they became more considerate.

Down here I am studying, alr stressing enough being unable to complete revision on time, with about a million concepts I realised I never knew (alright, maybe not that bad). 
Down there just across the block, those renovation workers blasting their opera-like Chinese music with those high pitched vocals.

OHMYGOD ! Getting on my nerves cos it's interfering with my brainwave frequency (if there's such a thing.) 

Ultimately annoyed cos it's not the kind of music that my ears would find peaceful, I got up from my desk, rolled my math lecture booklet into a cylinder, went to the window, position my mouth at one end of the hole, and 'SHUDDUP LAAAAAA !'

I'm not sure if they actually heard me cos I didn't really shout that loud, it was more like a raised voice.

But about a minute after that, the music stopped !!!!! :D
I wonder if their speakers finally spoilt or not :)

They closed the windows :) !

YAYYYYY ! 

But still, the music starts playing again . Argh.

And I'm still hearing the music now. What if it isn't the construction workers ? Dammit. Argh shuddup already pleaseeeeee TT.

Who in the right mind would blast this kind of ear-hurting music ?? If it's live karaoke, they can just lose their voice temporarily and generate positive externalities everyone else. *disdainful emoji*
