5. Aaliyah, "Are You That Somebody?"
Timbaland never could stop showing off – couldn't resist flaunting the mastery of the man from the big V-A – but he really got out of hand here. "Are You That Somebody?" is a mind-warp of a beat, taking the Southern route to the world's pleasure zones. And only Aaliyah could be serene enough to make it float – a more nervous singer would have busied it up, but nothing ever stressed Ms. Haughton. She gets both goody-goody and naughty-naughty; in the video, she revives the medieval art of falconry. Everything about "Are You That Somebody?" feels deeply chill, from the delirious Prince gurgles to the finger-snaps to the answer to Gwen Stefani. ("Don't speak! you know that would be weak!") Aaliyah will always be that somebody and this will always be her song.
