Days gone by people used to do some gathering in night as there was not any TV and they started to sing this kind of singing with is now part of Potawri Culture. People usually arrange these kind of programs on their marriages.
I personally like it only to extent where is stay meaningful but unfortunately now a days it is hard to listen any thing like that. Akram was and is king of singing and never sing bulshit, like the guys are singing now a days.
