Rihanna established herself big-time in summer 2005 with her debut smash hit, "Pon de Replay," and continued to demonstrate her smash hit potential in subsequent years (e.g., "S.O.S.," 2006; "Umbrella," 2007). By the time of her third album, "Good Girl Gone Bad" (2007), she was a full-fledged international pop star with a regular presence atop the charts, from Germany to Japan.
