"¡Happy Birthday Guadalupe!," The Killers, Wild Light and Mariachi El Bronx (Island Def Jam)

U2 may rule the rock 'n roll world, and Bruce Springsteen may be The Boss, but The Killers are Kings of Rock Christmas, offering up their fourth original holiday single in a row for 2009. They seem to be intent on spreading their fervor for the holiday, having recruited Elton John and Neil Tennant for last year's single and this year getting help from Wild Light and Mariachi El Bronx for this fun love song to a Latin temptress with a Dec. 25 birthday. Rock, pop, mariachi and other Latin influences meld for this distinctive tune, though some of the lyrics fall back on Yankee stereotypes. They throw in a spoken bridge, a dramatic device going back to "Leader of the Pack" or even earlier. The only question now is whether they'll keep this up till they have an elpee's worth of tunes, as the saying goes. As in the past, this benefits the AIDS-fighting charity Project (RED).
