Christmas carols are a beloved part of the holiday season, and there is a wide variety of carols to choose from. Popular Christmas carols include "God Rest Ye Merry Gentlemen", "Away in a Manger", "O Come All Ye Faithful", and "Once in Royal David's City".

"Hark! The Herald Angels Sing" by Charles Wesley is one of the most rousing and best-known Christmas carols in English. It was published in 1739 in Hymns and Sacred Poems. The lyrics refer to ideas of war and peace, and its melody has been adapted by many composers, including Johann Sebastian Bach, Franz Liszt, and Felix Mendelssohn.

"Good King Wenceslas" is another popular Christmas carol that dates back to at least the 16th century. It tells the story of Wenceslas, Duke of Bohemia, who became a martyr after being killed by his wicked brother Boleslaw the Bad.

Other classic Christmas carols would include "O Little Town Of Bethlehem", which features a lyric by 19th-century Episcopal priest Philip Brooks, and "The 12 Days of Christmas", which was originally written as a song for Thanksgiving.
