Writer's Block: Name that tune

[Error: unknown template qotd]
Canto Della Terra by Sarah Brightman and Andrea Bocelli. I've been listening to it since October and I am so in love with it =) Sarah and Andrea are so amazing together, I wish they would do more duets together.

Again by Yui. I've been addicted to it since I heard it on the opening of Fullmetal Alchemist: Brotherhood back in February. Yui is so amazing and this is my favorite song by her.
