Coke Studio [querry]

Are they all folk/qawalli/punjabi type music? I heard Rockstar by Ali Zafar which was hilarious but I guess nobody else enjoyed it as there were a lot of negative comments and nothing like that repeated...

I'm not saying that it was bad. Instead I enjoyed it, but I want to know if I will be listening to a whole range of music or just this slow/stretched out style...

Let me know

ps I'm new to this show if you haven't caught on... so any background info would be great... for example why is everyone saying bring back rohail..who is he and where did he go?
