Another thing these songs have in common is that they possess what Mullensiefen calls a "circular quality." Basically, they repeat themselves a lot. So if you come up with a simple, repetitive melody (adding raspy, high-chest vocals doesn't hurt), someone, somewhere will get laid to your work. Meanwhile, despite having been rated as "better than sex" by Spotify users, Mullensiefen claims that "Bohemian Rhapsody" is one of the worst songs ever for actually doing it, because it has too many sudden changes and sections that demand your attention. Plus, it's a real mood killer when both participants start yelling "Galileo!" at the top of their lungs.
