Ar rahman's sufi compilation

I'm planning to start a compilation of the sufi songs of arr here. There is a great fanfare for his sufi songs in particular as he doesn't misses to inspire and make us all divine when we listen to them. I'm trying to put together the sufi songs by him as a list which spreads across languages.
Originally the sufi and qawwali songs are songs which are sung in the praise of allah ( The god ). Later sufi transformed as a sole mystic renderings about the god and his power. Qawwali in a way got a diversed range of subjects on which it is sung. It is used to sing about the god, love, nature, e.t.c., according to an article about sufism.
There are experts in the field who consider and argue that the both are same genre "Sufi" and qawwali is a part of it. I also take it that way.
