7. "Like a Rocket Man"
Bowie's been writing songs about space since 1969's "Space Oddity." His 2013 comeback album had "Born in a UFO," "The Stars (Are Out Tonight)" and "Dancing Out in Space," but he relegated "Like a Rocket Man" to the bonus tracks. That was an odd move since it's clearly superior than many tracks that made the LP. Like many of his space songs, the track is really about drugs. In the song we meet Wendy Cocaine and a twitchy narrator that "never paid her for a gram." In the end he's speeding around like a rocket man. For all we know, this is the great, lost prequel to "Space Oddity." We never did learn how Major Tom got hooked.
