You like besuray songs?
Well I agree - especially about Atif, Ali Zafar has a nice Kishor Kumar type voice but he is just another Atif Aslam singing pop songs.
They are both pop singers, so they don't need to be really in surr, just dress up nice, say somethings catchy, keep your fan following of 12 year old girls alive and voila - you're a hit.
That's the thing about India (well to be honest in Pakistan too but you don't notice the nonsense so much in Pakistan) that it blows out of proportion the C team of Pakistan, which is good for the C category singers, but you've seen through Coke Studio n all, the real talent is elsewhere and the impression may come off that these are our best singers going to India whereas that's not true.
I think other than Junoon and NFAK nobody else that went to India and got fame was really worth that acclaim. Then too only the really happy go lucky songs of both Junoon and NFAK are known to Indians not the really deep ones.
