Suggesting that "Promiscuous" was a jarring change of pace for Nelly Furtado would be an understatement. As the lead single from her Timbaland-produced "Loose" album in 2006, the sexy, thumpy number was a far cry from the more earnest, quirky singles of her first two albums -- including "I'm Like a Bird" and "Turn Off The Light." But sexy clearly worked, as the cheeky "Promiscuous" tune spent eight weeks lodged in the No. 1 slot. It was the first of two toppers from "Loose" -- she later returned with "Say It Right."
