This song isn't New Jack Swing.

I hate how ignorant people try to label every rhythmic dance song that was released between 1987 and 1993 as "New Jack Swing," simply because that was the era it existed in.

Paula actually had some NJS songs here and there ("Straight Up," "Knocked Out," "The Way That You Love Me," "Promise of a New Day"), but this wasn't one of them. "Cold Hearted" is just standard late 80s dance/pop, and one of her poppier tunes. That being said, the song is still 20x better than the dance/pop of 2008-present, and shits all over the Gaga's/Katy's/Rihanna's/Kesha's of today.
