Azgar Bhai,
I have seen the first of the three videos (The King of Qawalis-Chapter I) and here are my comments.
1. Please try and paste the name of the Film and Year at the top right corner.
2.See if you can improve the selection of Qawalis. For instance, there are three on Rishi Kapoor. Maybe, you can have just one or two on Rishi Kapoor, including 'Parda Hai, Parda Hai'. In my view, Parda Hai Parda is a better Qawali than the ones you incorporated.
Similarly, select some other B/W ones such as, for instance, "Meri Tasveer Lekar Kya Karoge" from Kala Samundar(1962)--N.Datta. In my view, this can even replace that Qawali on Vyjayantimala.
Just my personal views. Not necessarily sacrosanct.
