Shreya Goshal Prime Time As Playback SInger Has Gone?

You know what, its honestly better than the great ones like Shreya, Sonu, Sunidhi, KK, Shaan don't sing in today scenario. 

I wouldn't be able to hear them sing crap.

And to answer you, their prime didn't really go, they were sidelined and removed slowly from mainstream work as below average shit took over.

Shreya is not restricted to bollywood alone.She sings in almost all the languages with utmost perfection from whatever I know about her discography.Her pronunciation in Tamil and Malayalam is perfect.A non South Indian to perform like her in South is nothing short of brilliance.When it comes to bollywood,her ghar more pardesiya was like a gem among today's remix crap.

That being said,as long as SLB is making films,I am sure he will give Shreya brilliant songs like Bhairi Piya,Dola re,Pinga ,Ghoomar and so on.Her strong classical music foundation will make sure of that.No other singer of today's generation has made that kind of an impact like that of Shreya and they wouldn't feel right in SLB dramas

As long as she gets offers nothing is over 

Not really, it  is just that other singers are doing some great work
