17. "Girlfriend" (2001)
Producer: Alicia Keys, Jermaine Dupri
Album: Songs in A Minor
Ol' Dirty Bastard was an idiosyncratic, weird but lovable member of the Wu, and Alicia Keys was a highly-hyped songstress. Somehow mixing the two together worked on "Girlfriend." Keys samples the gritty "Brooklyn Zoo" and also manages to score a banger like ODB did. As rugged as the beat is, the then-debuting singer sounds far from overwhelmed.
