BRAND NEW: Collectable you will love. Music and Christmas are always associated with each other. From quartets singing carols on street corners to orchestras filling the air with majestic Christmas symphonies, music celebrating this special time is found the world around. A Christmas carol is a song whose lyrics center on the theme of Christmas. Traditional Christmas carols focus on Christian celebration of the birth of the Christ Child. Other Christmas songs focus on more secular holiday themes, such as winter scenes, family gatherings, and Santa Claus.
