Pop singers and drama OSTs?

QB & Bilal Khan are both fairly new. I think both have gotten great opportunities with their respective OSTs. & both of them have only sang one OST each thus far.

As far as your question goes. I don't see it like that.

One can't expect Sanam Marvi or RFAK to sing every OST there is. They're voices don't suit every kind of music genre there is either. & they can't sing every OST..With that said, I feel the youth connects with any OST that's good to the ears, regardless of it being pop, rock, classical etc. It really has nothing to do with the genre. Every RFAK song be it an OST or one his bollywood songs etc, the youth usually does connect with it..in fact people of all ages do..because he gets good songs. All of Sanam Marvi's OSTs do pretty well..Paani Jaisa Pyar from what I can think of now, was a pretty big hit amongst everyone for the most part.

So, I feel it all just has to do with the type of song for the most part. If the OST is good (from lyrics, to music and then yes the singer too)..people appreciate it. Certain singers suit certain kinda songs..and it more or less has to do with promoting anyone who has the talent to sing well.
