Taylor Swift's The Life of a Showgirl features one of her raciest songs to date with a track titled "Wood." "It's a love story," Swift, 35, said in an Amazon Music explanation video shared on Friday, October 3. "[It's] about using, as a plot device, popular superstitions [and] good luck charms, bad luck charms and all these different ways we have decided things are good luck or bad luck - like knocking on wood and seeing a black cat. That is the way I've decided to explore this very, very sentimental love song.
