Yayyy a fan! Surprised it's you, lol, but a fan nonetheless. I haven't heard everything on your list (of course that means I'm downloading them immediately) but yah, I totally agree with the emotions thing. Especially when singing stuff like My Heart Will Go On and Because You Loved Me...when she reaches those really high pitches, she's almost screaming and you can really tell that she means every word of it!!
I must announce: My Heart Will Go On is THE MOST BEAUTIFUL song ever sung...ever!!!
But what about things like The Little Mermaid (Jodi Benson), that part where she gives her voice away and it's just "Ah-ah-ah, ah-ah-ahh"...those things are really nice too.
Edit: I'm listening to her live right now...LIVE. Goddam, she's amazing! I can't get over it...it's LIVE!!!
