As in love lost and gained, the yin-yang of popular song. Green, Jill Scott’s former backup vocalist, doesn’t come up with any new twists on the old formula. But the young Philly soul singer does offer a fresh delivery on her debut album. “Fanatic,” which compares love to “some bad habit,” conveys a desperate yearning, while “Emotional Rollercoaster” hits unexpected highs and lows vocally. But “Superwoman,” with its staccato delivery and assertive message, provides the album’s most dramatic moments.
