Singing, most definitely -- I'd classify it as a typical modern praise song, sounding like something a modern solo singer with a fairly large vocal range might have written fpr solo performance. It does not really seem to be written with harmony (even though there were bots of harmony here and there) or choral singing in mind.

I think that's the issue -- it's just not ideal material for a large group to sing. Given the song's range of more than an octave and a half, some of a mixed-voice audience are bound have to shout (overextend) to reach the high notes, or bottom out to hit the low ones. And then there's that relentless aerobics-type accompaniment that makes one feel one must plunge recklessly into the exercise of singing. The volume of the accompaniment and its frenetic pace would I think encourage both immoderate volume and poor vocal control.

My armchair analysis. Now, must hunt up some lovely old Welsh hymnody for recovery purposes...
