Sure, we're all goofy over the latest failed rapture prediction, so Facebook is full of links to Blondie's "Rapture", but may I humbly suggest a substitute, just to mix it up a bit? My first instinct was Larry Norman's "I Wish We'd All Been Ready", a classic futuristic look at the rapture, thinking of those left behind by the event, but Norman's brilliant and strange Christian rock career probably deserves better representation than that somewhat embarrassing track.
Instead, who better to warn of the forthcoming apocalypse than the Wu-Tang's GZA/Genius, with "Basic Instructions Before Leaving Earth"?:
