I'm not heavily involved myself, but some of my close friends are deep into the Christian music scene here in LA (and local independent music in general). We've talked about pirating and what the various bands they know think of the practice, and the answer has been pretty much unamimous. Of the dozens of Christian bands that my friends know, every single one of them prefers the additional exposure that pirating brings to whatever marginal revenue is lost in sales.
I go to shows occassionally, and I remember specifically telling my friend who took me to see Eleventeen: "I'd better not tell Josh that you burned me a copy of their last CD."
He just laughed. "He doesn't care, he'd probably be glad to hear that I like them enough to make you listen. Now you're here at the show, and paying for that."
Yesterday I went to Lighthouse Christian Bookstore in Long Beach, and I was stunned that all the music I was interested in was $6-$8 more than it is at Tower Records. It used to be that you couldn't find any of the indie/Christian stuff anywhere but at a Christian store, but that's not the case anymore; I wonder if they'll be able to stay in business?
