The voice of Nusrat Fateh Ali Khan was Sufi voice and that is most popular among the music lovers, In india some singers are trying to get that or singing in the Sufi voice but the passion we found in the voice of Nusrat, we can't see till now.
Hmm my favourite female singer is Rihanna and don't really listen to males but Breaking Benjamin undoubtedly are the best band!
