Día de Muertos is a Mexican holiday celebrated from October 31st to November 2nd that focuses on gatherings of family and friends to pray for and remember loved ones who have passed away. As part of the celebrations, people create ofrendas or private altars honoring the deceased with sugar skulls, marigolds, and the favorite foods and drinks of those being remembered. They also visit gravesites and leave gifts. The music played during Día de Muertos is typically upbeat to celebrate rather than mourn, often performed by mariachi bands. One such song is "Cumbia de los Muertos" by Ozomatli, which describes spirits of loved ones dancing together happily.
