Forget comparisons to Billie or Chaka -- that craggy-yet-smooth croon is Erykah Badu's own. Little here on Worldwide Underground matches the impact of ''Danger,'' with its simple piano figure and snatches of a fake 911 call. Still, most of this succeeds: ''Love of My Life Worldwide'' (with Queen Latifah) neatly reconfigures the Sugar Hill sound, and ''Back in the Day'' (with Lenny Kravitz on guitar) rides high on a strong backbeat.
