Toxic (2004)

Six years after finding breakout success with her …Baby One More Time single, Britney Spears proves she’s still the pop star to top with Toxic (2004), the second-biggest U.S. hit of her career. Voted as the planet’s all-time second favorite song in a recent global survey, Spears’s smokin’ single describes a scintillating affair with a married man. Boasting countless remixes and cover versions, Toxic is boosted by a memorable music video, which sees Spears donning a flight-crew uniform, a pleather catsuit, and––at one point––hundreds of meticulously affixed diamonds. All three outfits prove effortlessly seductive, as Spears radiates irresistible sex appeal over the course of the video’s finger-licking three and a half minutes.
