Music for Slideshow

I volunteer at a week long summer camp.  As part of my responsibilities, I have self designated myself to take photos for a nightly slideshow to be shown before each evening devotional.  I have found it is incredibly difficult to find clean secular music without cursing and references to sex, drugs, alcohol, suicide, etc.  I spent the better part of the evening going through a music library trying to find appropriate music for a Christian camp. I understand the idea of a blank check the artist should have for musical expression.  However musical artists should understand that they are limiting their audience by making unclean references in their music.  You can still have good sounding clean music!
