My submission for the contest is "This One's for the Children." Check out the video for its gaudy display of righteous multi-culturalism. NKOTB is pretty serious about letting us know that this one's not just for American children, but all the children of the world. The song's lyrical gem: "Many people are happy / many people are sad."

(Full disclosure: As a kid, I definitely bought the complete NKOTB Christmas album from which this came.)
