a little myriad of thoughts really:
Angels are suppose to sing all the time with or without the prescense of god correct?
Than what would a warlike angel sound like.
Uriel for example is feared more than most angels for his fierce war cry, but can he sing?
I rather doubt he has the limited voice of a base or a second tenor(to spite mankind(. I rather doubt he has a counter-alto voice (to spite womankind).

Anyway, I am proud (naively so) and apprehensive to say I have ghosts from my past to haunt me and keep me from sleeping. It somehow makes me feel less sheltered and more normal...
