If I am a Christian, that is an Engineer...

Should I allow secular artists / musicians to record at my studio? I'm a businessman and my business is to record artists in need of some engineer, producing and so on. If that okay, if its for business?

I know we have talked about being a "Christian Producer". The Ham Sandwich Show talked about Christian's using their God given talent to create music for secular acts (i.e. a band member for Jay-Z).

And when I say secular, I also mean; non-christian, cussing, spiritual (but not religious), etc.
