I don't know about the originality of that pakistani song but what I know is Mukti's music in that song is not original, yet he bagged 4 awards. Apart from that, Alamgir is an old singer and the fact is it has been very long that he left singing. So you guys / gals can judge about the originality of that song.

I don't think that song is in youtube but it's rendition is in youtube. Link is

Just listen to the music and it does match with Mukti's song.
