I think she sounds best when she does mid-high or higher notes. Those always stand out and she makes them sound nice-sometimes even easy. Her voice has also aged very well also. Examples: I Get Lonely, Rhythm Nation, He Doesn't Know I'm Alive, Black Cat, Escapade, I Know the Truth, Love Will Never Do and plenty of others. Her airy/breathy vocals are also really nice because her voice is soft and she's always been the best with harmonies. With All For You and Damita Jo she shows it a lot I think. Of course she's done them her entire career. Examples: All For You, FHTF, Anything, Feels So Right, China Love, Spending Time With You, All Nite, Make Me
