Well, "Danse Mon Esmeralda" was stunning, so I'll say one of my favorites.
"Tu Vas Me Detruire" ("You Will Destroy Me")
I'm also in love with the English version!
"Your Love Will Kill Me"
(When I typed that one into the search bar, one of the top videos on the list was the Phantom of the Opera vid that turned me onto the English translation in the first place...tee hee.)
