Rihanna has become one of the most successful singles artists of our time thanks to her singular voice and charisma, as well as a small army of producers and songwriters that are itching to work on her next chart-topper. But she’s become an increasingly discriminating artist, turning down a number of surefire hits to pursue a more unique and personal sound. In the process, dozens of artists have wound up releasing the Rihjects that were pitched to Rihanna. Some were massive hits anyway, like Sia’s “Cheap Thrills” and Miley Cyrus’s “We Can’t Stop,” while some songs never found their way to a voice that could occupy Rihanna’s unique combination of dancehall, hip-hop, and EDM.
