Joey Negro does it again with a pumping edit of this heavily sampled classic from Phyllis Hyman's 4th album, originally produced by RnB heavyweights James Mtume & Reggie Lucas. You can find this on one of the million or so compilations Joey Negro has out at the moment, this one on the upcoming Remixed With Love Vol. 3 on his Z Records label.
