14. "Heathen (The Rays)"
The title track to Heathen is an incredibly dark song that wraps up an incredibly dark album. "It's about knowing you're dying," Bowie said. "It's a man confronting the realization that life is a finite thing, and that he can already feel it, life itself, actually going from him, ebbing out of him, the weakening of age." Bowie was a perfectly healthy 55 years old when the song came out, but in just a couple years he'd be fighting for his life after a horrible heart attack.
