"And Mary said: 'My soul glorifies the Lord and my spirit rejoices in God my Savior for He has been mindful of the humble state of His servant. From now on all generations will call me blessed for the Mighty One has done great things for me - holy is His name.'"
Virgin's Lullaby - Nativity Voices
This song is from the Polar Express, which is one of my favorite Christmas movies (mainly due to the soundtrack from it); which is why I like this song a lot. It is also another song with a great balance of two voices.
