After having spent many years of my life leading worship (high schools, colleges, vocationally, etc), a problem that was always personally vexing were the 2 camps warring with one another – classic vs. modern.  Anything the worship leader did was immediately met with criticism.  Then in the late 90’s, there was a blending of the two that begun to erupt, and it was good.  It would be modern worship leaders playing hymns with their modern musical arrangements, which was usually “Be Thou My Vision” or "Come Thou Fount of Every Blessing" by way of Coldplay B side.  It seemed to satisfy theology heads –they got to sing words that were penned in a poetic, longer-than-30-second made up journal entry that repeated constantly, but it gave the modernist digital delay guitar effects ever present in their songs.
