Wow, that question can be tough with so many great artist out it's hard to choose. My favorite two at the moment are Tedashii and Da T.R.U.T.H. Both of them brings such a unique style of rap that just engage and provoke you to action! Whether it is to staying committed to the faith or being free from sin these brothers bring in straight hard at you! When I listen to their music it always put me in the mood to want to serve God with more tenacity and intensity which in my opinion is what music should do.
