7. Mariah Carey
Band Or Solo Artist?: Solo
Genre: R&B, Pop, Soul

Mariah Carey is an OG diva, and we think she'd actually appreciate the title, in the sense that she's one of the most celebrated singers of all time. There aren't many songbirds that possess the vocal range that Carey was able to weave through her pop hits and make way into nearly every genre of the industryâ€”pop, R&B, hip-hop, and even a few classical hits here and there.
Carey has sold more than 200 million records worldwide and, in 1998, she was honored as the world's best-selling recording artist of the 1990s at the World Music Awards.
