White Christmas is a classic Christmas song written by Irving Berlin in 1942. It was first performed by Bing Crosby and became a popular holiday song. The song talks about a snow-covered Christmas, and it's a perfect example of the cozy, nostalgic feeling that comes with the holiday season. The lyrics mention all the things that make Christmas special, like the sight of a white Christmas tree and the warm feeling of being surrounded by loved ones. It's a timeless classic that always puts me in the Christmas spirit.
