Released in 1957, Elvis’ Christmas Album is the top-selling holiday release of all time with 9 million in sales, according to the Recording Industry Association of America. The single Blue Christmas — the one track Elvis didn’t want to record — is a Christmas classic, even parodied by Porky Pig. Other Christmas blockbusters are Kenny G’s Miracles: The Holiday Album (8 million) and Barbra Streisand’s A Christmas Album (5 million), according to the RIAA. But the Christmas kings, at least in terms of sales, have to be Mannheim Steamroller with two albums topping the 6 million mark: A Fresh Aire Christmas and Mannheim Steamroller Christmas.
