Rihanna

For her third disc, "Lil Miss Sunshine" stakes a claim as the queen of R&B by turning to the '80s. On "Shut Up and Drive," she samples New Order's "Blue Monday," while lead single "Umbrella" -- with Rihanna's understated, nasal vocals wrapping around dramatic strings -- would fit nicely in a John Hughes flick. The spunky "Breakin' Dishes" is more fun than bitter, and "Rehab" overcomes its rather mawkish sentiments to be an effective break-up ballad. There's hardly a throwaway track, and Rihanna continues to evolve. This edition includes three unreleased tracks, including hit "Take a Bow." This version also contains exclusive live bonus tracks from Rihanna's appearance on FNMTV.
