It's all in your heart, some people don't like doing the crossover thing some do it's a matter of what your personal beliefs are. Me personaly, as dwdrummer put it, I wouldn't mind playin with some of the main stream pop or r&b artists, but artists who music is filled with garbage like hardcore rockers and yeah some r&b cats, I don't think I could play for them, but cats who grew up playin in church are every where, G. Hayward, Paul John, Nisan S., teddy campbell, gordon campbell, and many others, I read in some interviews of mainstream drummers that they know that some of the real talent is in the church,
