I figured it wouldn’t be part of their aqeedah, i guess its just that its mostly harri pagRhi followers who happen to be doing most of the disturbing. And no, we dont get to hear songs at all… as for the other groups you mentioned, i rarely hear stuff from them lasting all night long… its mostly naats.
I cannot explain how huge and loud the speakers used during rabbi-awwal are 
and if someone’s positioned it between a line flats then its just too much…
like i said, the imams of such groups should really take a stand on the matter and stop the practise… or maybe they already have and their followers just dont follow…
