Why Lauryn Hill Should Collaborate With Him: These two have a rich history together. They co-starred on the 1996 hit, "If I Ruled the World (Imagine That)." And they also co-starred on the Life Is Good/Black Rage Tour last year. So getting them into a studio together might not be all that far-fetched. Once there, we're willing to bet that the magic they've made together in the past would resurface again.
