Song at the swimming pool?

Looking for a song NOT listed in the end credits - I checked all the tracks one by one, it's not between them. The only song I didn't find anywhere is "Kiss Goodbye" by Butterfly 88, so it's possible to be that one.
Scene description: Harvey Keitel & Timothy Hutton by the motel's swimming pool, 19 minutes into the film. Mellow with a female vocalist.
Can anyone help?
