iTunes sends me little love notes throughout the week, and today I idly clicked on "What Light," the only available cut from Wilco's forthcoming album Sky Blue Sky (Nonesuch, due out May 15).

I thought about buying it and then I saw a review saying something to the effect of great song, but hey, save a buck, Wilco has it as a free mp3 for download on their website.

So I went and they did so I did.

Your turn.
