Long time

I think that he takes his own time to come out with his music. And i am sure that you or even anyone for that matter isn't disappointed by the quality of music that he comes out with. He takes time just to bring out good music and dont lets his standards fall down. he is not like Himesh Reshammiya, who comes out with 4 films at a time and none of their music is worth listening even once.

To get successful copying of fine tunes without the knowledge of others and mix it with his knowledge to make unique in the music world. Every successful person learns from old legendaries. Do you got it!
