Dear Titangeek, I hope you don't mind if I petulantly insist that Nightwish, when Tarja Turunen sang with them, WAS magical; now, they are just good...
Anyhow, Tarja, of course, Isgaard, Loreena Mckennitt, Sarah Brightman, Sarah MacLachlan, Josh Groban, Andrea Bocelli, and, of course, Azam Ali and Lisa Gerrard; and I just downloaded the Bob Segar albums that iTunes has FINALLY offered, and Rob Halford had and Freddie Mercury had simply amazing voices!

True, her voice just fit better with the Gothic/fantasy style of there music. Wonder how Imaginaerum will tern out.
