Would you hit it?
Good speculations, DreamSparrow. That first quote is interesting. Of course, Roslin and Baltar are the obvious choices. But just to throw out another... Gaeta? He has the guilt of lying about Baltar during the trial. Now he's endured being shot, suffering for weeks, and losing his leg. And they made a particular point about him singing to distract himself when the pain became unbearable, which would fit with both the "howl of suffering" and the general connection between music and Cylons. And he was shot by another Cylon, which would add a poetic element of Cylons fulfilling a Cylon prophecy.
