"O Holy Night" is a sacred song about the night of the birth of Jesus Christ, described as 'the dear Saviour' in the original, and frequently performed as a Christmas carol. Originally based on a French-language poem written in 1843 by poet Placide Cappeau, it was set to music by composer Adolphe Adam in 1847. The English version, with small changes to the initial melody, is by John Sullivan Dwight.

Merry Christmas is the fourth studio album by American singer-songwriter Mariah Carey, and her first Christmas album. Released by Columbia Records on October 28, 1994, at the peak of the initial stretch of Carey's career, between Music Box (1993) and Daydream (1995), the album features cover versions of popular Christmas songs in addition to original material. Carey worked with Walter Afanasieff, with whom she wrote all of the original tracks, as well as producing Carey's interpretations of the covered material. Three singles were released from the album, of which "All I Want for Christmas Is You" went on to become one of the best-selling singles of all time and the best-selling Christmas ringtone in the United States.
