What You Won't Do For Love - Bobby Caldwell

This song is in a commercial now (I forget what) so I hear it a lot.  The version they use on TV has a stronger base line. I've always loved the song, which is from 1978.  Researching the song on Wikipedia, I find that it is an example of a genre called Quiet Storm. (Named after a 1975 Smokey Robinson song.) It will be interesting to research this genre further.
