I am looking for the name of a Luther Vandross song that was played on an episode of the show Step by Step?

I am looking for the name of a really nice Luther Vandross song that was played on an episode of the show Step by Step. It was the episode where Dana ends up at the apartment of some sleazy guy and gets uncomfortable with his sudden advances. Anyways, he plays a really nice song on his stereo and says he loves Luther Vandross while the song is playing. The name of the song is not mentioned. Anyone know what I am talking about? Thanks for your help.
