What is cultural theology exactly?

I get stuck thinking about some strange things at times. Most of it is me chewing on Christianity. Trying to define why I believe what I believe and how it all fits into my life. I have noticed in some recent trips to my local bookstore that books are emerging which examine how Star Wars provides wisdom into Christian living and other similar titles. Now, I am not a stick-my-head-in-the-sand Christian who wants to disassociate from society. Nor do I think we should not have a reasonable dialogue with our culture. In fact, we should be more influential in culture than we are! But it seems like we have a growing tendency to put things in the wrong order when it comes to "cultural theology". Instead of seeing a hidden "God meaning" in movies, music, and art, we need to be diagnosing the illness being declared by most of these genres. Instead of relating Eminem lyrics to Christian thought perhaps we are better served by understanding why Eminem is having such influence and his message is resonating so well with out youth and then demonstrating how God can have the same influence (as well as the answers to the roots of brokenness expressed).

So, how do we do it? How do we communicate the frustration and angst of the generation that is consistent with the gospel message? Does God not understand these emotions? What is the Christian response to "Gangster Rap"? Is it simply a judgmental denouncing as "satanic music" or are we willing to engage the sources of frustration that the artists are conveying; and offer a solution!
