Few celebrity siblings can emerge from the shadows of their already famous relations to become superstars in their own right and with their own distinct personalities. That's exactly what Janet Jackson did in becoming one of the biggest female pop and R&B stars of the '80s and '90s. Since her breakthrough in 1986 with the album Control, Jackson's career as a hitmaker has been a model of consistency, rivaling Madonna and Whitney Houston in terms of pop chart success over the long haul. A big part of the reason was that Jackson kept her level of quality control very high; her singles were always expertly crafted, with indelible pop hooks and state-of-the-art production that kept up with contemporary trends in urban R&B. Once established, her broad-based appeal never really dipped all that much; she was able to avoid significant career missteps, musical and otherwise, and successfully shifted her image from a strong, independent young woman to a sexy, mature adult. With a string of multi-platinum albums under her belt, she showed no signs of slowing down in the new millennium.
