Christina Perri - A Thousand Years
Saving Jane - Immortal (and possibly I'm in Love With a Vampire)
Barenaked Ladies - It's All Been Done
Indigo Girls - Galileo
Pretty much all of Queen's It's a Kind of Magic (but particularly Princes of the Universe and Who Wants to Live Forever)
Tempted by Muse's Supermassive Black Hole, but that may be cheating.
About every other Evanescence song (but particularly My Immortal and Bring Me to Life)
Cheryl Wheeler - Gandhi/Buddha
Any suggestions? I know I'm forgetting about a thousand songs. . .
