Music and modesty

I had an interesting thought today that seems to tie together two seemingly disconnected things.  As i am as big fan of music, the philosophical grounds for music and the worldviews behind them are of interest to me.  I believe i have observed in the Protestant world the pattern of being about five years behind the creative curve.  For the most part (a very large part), most Christian artists are not original or creative, they simply imitate, usually poorly, what is happening in the world, but they are about five years behind.
The second point that occurred to me is that in the world of clothing and modesty the same type of mentality is occurring.  The Protestant world, American evangelicalism, has no standard for modesty, it merely follows the lead of the world, but only about five to ten years behind. If one was to survey a large number of Protestant pastors, i fear that about 90% of them have not given modesty more than a cursory consideration, if at all.  The remaining ten percent may have a definite position, but that position is probably not based on an objective standard but a personal, subjective one.  Maybe I'm wrong, hopefully i am, but looking at the way the modern American teenager and young adult dress agrees with my conclusions.
My final question is, is this a pattern that we will see elsewhere, if we take the time to look?  I believe these observations for perfectly with the modern evangelical worldview, that of making oneself the final authority, interpreting Scripture for oneself.
