Lauryn Hill's honey-dripped voice helped popularize '90s hip-hop group the Fugees, but she took that voice and made a name for herself by going solo in 1998 with critically-acclaimed album 'The Miseducation of Lauryn Hill.' The album was a massive success commercially, as well, earning the beautiful singer five Grammy awards.

The old rule of supply and demand applies here, though, as Ms. Hill didn't release another album for four years, at which point audiences were clamoring for her return. Hill's popularity off the back of just one album more than proves her power and worth.
