Brother KS Yes you are right the Five percenters are clear kafirs but the article I linked to also mentions some Sunni rappers. Plus often you'll find that a lot of the NOI or 5%ers eventually become orthodox Sunnis.
Brother the above link is to the 5 %er sect who are KAFIR. That is not Islamic at all. The founder was a former member of 'Nation of Islam'. He left and claimed to be Allah (wali'yadhubillah). Then each member claims he has the power to be God. They state (Allah destroy them): A = ARM L= LEG L =LEG A = ARM H=HEAD I have only quoted the above so you know the enormity of their kufr. When Busta Rhymes says he is Muslim he means this kafir group.
:s1: this is an interesting academic study of how Islamic rappers have become mainstream in the USA: http://comp.uark.edu/~tsweden/5per.html
