9. Jose Feliciano/Feliz Navidad
Total plays per season: 15,320
When it was released in 1970, Feliz Navidad was a great Spanish lesson and, if nothing else, taught a few families the translation for "Merry Christmas and Happy New Year." More than 40 years later, though, it gets a bit repetitive. Feliz Navidad is repeated 21 times and "I want to wish you a Merry Christmas" is sung 18 times during the course of a three-minute song. Inflict that on an unsuspecting population 15,000 times and you're dangerously close to committing a war crime.
