Haven't watched the video yet, but wanted to chime in on the Bocelli comment. I absolutely hate opera, but I could listen to Andrea Bocelli for hours. One of the most beautiful voices I've ever heard - every time I listen to "The Prayer" (never mind the fact it's got Celine Dion - possibly the only song she's on that I like), I get choked up.
Josh Groban does the same thing, on songs like "You're Still You" and "Home To Stay". Not very metal to admit this, but fuck it, we all have divergent tastes.
