n What’s the world’s most played song? There’s probably no way to get a definitive answer, but Lu Hughes of Walnut Creek, Calif., nominates “It’s a Small World,” which is heard at the attraction of the same name in Disney theme parks worldwide. She figures there’s no time when the song isn’t being played somewhere. Have another nomination? Please let us know.
