BEST INTRO – Beyonce, "Sweet Dreams": While it’s hardly original to borrow Brahms’ 240-year-old “Lullaby” melody, Beyonce and her songwriting crew showed more than a little creativity by twisting it into something menacing enough to lead into that creepy (and killer) bass line.Honorable Mention: Lady Gaga, "Bad Romance"; Kings Of Leon, "Use Somebody"; Jay-Z feat. Alicia Keys, "Empire State Of Mind"Disqualified: David Guetta, for straight ripping off Coldplay’s “Clocks” for the intro to “When Love Takes Over.”
