This week's S4S isn't actually a song, but it is music. "The Opposite of Forecasting" is Austin, TX's Weather, Sonified. It's a project by Douglas Lausten <Lownote.net>.
Let's see whether I can add a player: -- yup! Can't seem to apply any styles to it, though, and I have no idea whether DW will allow it.
Credit for finding today's s4s goes to siderea.
