02 Britney Spears - Womanizer
You say I'm crazy? I GOT YOUR CRAZY. Perhaps the most anticipated single of the year (and when we look back on the decade years from now, we could most likely say most anticipated of the decade) is Britney's 'Womanizer.' This marked the true return of Britney. Britney came back fightin' with a FIERCE track and HAWT video. When's the last time anyone's seen Britney lookin' good naked? Certainly not in 2007. But 2008 was Britney's year. She scores just her 2nd #1 on the Hot 100 and her 4th #1 on mainstream radio, putting Womanizer in the ranks of Baby..., Oops!, and Toxic, obvious Britney classics. Womanizer is no different. It will go down in history as one of Britney's greatest singles ever, and rightfully deserved. All hail Britney and this iconic piece of pop art...WOMANIZUH!
