Smooth Jazz CD 101.9 (it was on in a restaurant; I didn't decide to listen) has pushed the envelope on defining its format. A recent playlist selection: "Fields of Gold" by Sting.

CD 101.9 has integrated many pop, adult contemporary and other crossover hits into its playlist--fairly, because many pop songs can legitimately be presented as jazz. Joe Jackson's "Steppin' Out" and Sade's "Smooth Operator" come to mind.

The definition of jazz eludes technical specifics (it doesn't just come down to complicated chords, though that seems to be a reasonable starting point), but "Fields of Gold" is simply too linear for this label. What next, "Stand" by REM?
