yeah, all I can do is tell you what I have or listened to. Just start with a christian music retail site or site with christian rap and just start listening like most of us do. And find the groups you would like.
Though, there are two DJs that will give you good ideas on Djing hip hop and Skillspinz, if I remember is part latino as well. I have a cd of his and love it. DJ Maj is great too.
