In the United States of America, Christmas music generally begins to play after the Thanksgiving holiday, when most of the shops around would start displaying Christmas decorations. The US music industry makes around 40 percent of its annual income through Christmas music. The demand for Christmas music just before the actual day is high, and injects a spirit of Christmas into everyone. Hundreds of radio stations across the United States play Christmas music around the clock to keep everyone hooked to their radio sets. "Jingle Bells", "We Three Kings" and "Santa Claus is coming to town" are the most popular Christmas melodies.
