Song-That's-Stuck-In-My-Head of the Day

I don't know where this one came from but I've been singing it all day. Of course originally by Johnny Cash and June Carter but Joaquin Phoenix and Reese Witherspoon do a really fantastic job covering it. In fact I'd say it's more of a copy than a cover. So get a little western today, throw on the chaps, bust out those spurs, and throw down a few cowboy steps to "Jackson".
