I woke up with this song stuck in my head again this morning and so, accordingly, I attempt to exercise it here. Aretha Franklin's cover of Kenny Loggins and Michael McDonald's classic yacht-rocker made popular by the Doobie Brothers is a manic slice of synth-indulgence that's, like many an Aretha song, dead catchy. Beware. Just give it thirty seconds of warming up and you'll be in the zone, the smoooooth R&B zone.
