What are good rap songs that are not played on the radio?

Becoming a youth minister, I have to stay "hip" as they say and be able to "get jiggy with it" I guess I am saying that right:) Have you heard of Christian rap? The best there is! The-Hip Hop Church and Bible Rap are offered on www.Christianbook.com and GRITS as well as Andy Hunter, a youth minister turned rapper. I hope that this has helped. Good luck and God Bless:)
