Rucker is a student of American pop music. His catalogue reflects that—even beyond the big genre-crossing hits. "I Don't Care," with Brad Paisley, offers tongue-in-cheek country rock accented by pedal-steel guitar and barrelhouse piano. "Sometimes I Wonder," meanwhile, recruits Jill Scott for a neo-soul duet that pairs smooth horns with even smoother harmonies—some of the most sensuous vocals of Rucker's career.
