Over at Andrew Sullivan's blog, there's an ongoing discussion of whether church can be "hip," which has morphed into a discussion of what, if any, good "Christian music" there is out there.
Now, I've been skeptical of the whole category of "Christian music" for a very long time, and was pretty well convinced that there was no such thing as genuinely good "Christian music," insofar as Christian rock has a tendency to vulgerize and trivilize the subject of Christian faith. The paradigm example of what I mean by this are the so-called "Jesus is my boyfriend" songs (wickedly satirized by the South Park "Faith +1" episode).
As it turns out though, for a number of musicians who are Christian in a less narrowly defined and rigid sense of the word, there's some genuinely good music being produced. Sully's blog mentions, in particular Belle & Sebastian, Pedro the Lion, and The Mountain Goats. He also points to a post by Daniel Radosh listing 10 great examples of Christian music.
