“White Christmas” - Bing Crosby

It may come as no surprise that the best-selling single of all time is one of the oldest songs on this list, as well as another Christmas classic. "White Christmas" has sold over 50 million copies worldwide and continues to be a holiday chart success year after year. Bing Crosby's perennial hit was first released in 1942 and was repeatedly reissued by record label Decca, making its annual appearance on the music charts an annual tradition.

Since its release, "White Christmas" has been covered by a variety of artists, with Bing Crosby's version being the world's best-selling single (in terms of physical media sales), with estimated sales in excess of 50 million copies worldwide. When the sales of other versions of the song are added to Crosby's, the song's total sales exceed 100 million.
