Steve Earle has never been known to keep his opinions to himself -- especially when it comes to Music Row and the pop/country music that permeates much of country radio's airwaves.

He's called Garth Brooks "The Anti-Hank" -- referring, of course, to country legend Hank Williams. He's referred to Shania Twain as "the highest-paid lap-dancer in Nashville." So why would he have a midriff-baring poster of Shania hanging outside his office door?

Take a closer look and you'll see the word "talent" handwritten on the poster with an arrow pointing straight at the Canadian beauty's bellybutton.

Just a guess, but we're assuming his feelings for the one-time CMA Entertainer of the Year haven't changed.
