Needless to say, Himesh Reshammiya is the master of Sufi Rwak in post ABA era.
These songs have hard core Sufi Rwak underlying beats n orchestration, underlying beats don't get more hard core Sufi Rwak than these:
> Mere Lamhon Ki Aarzoo - Aap Ka Suroor
> Ahista Ahista Title Trax
> Kola Laka Vellari - Welcome
> Teri Yaad Bichaake Sota Hoon - Rocky
Most importantly, it is the beat pattern and the raw rugged texture of the synth used in the beat pattern which gives a hard core Sufi Rwak flavor, which is very typical of this genre.
