Taylor Swift has definitely diversified her cover songs on her current "Speak Now" tour.  In Atlanta a few weeks ago, she was joined on-stage by rapper T.I. and this past Wednesday night in Austin, TX, she did a 180 and she brought out folk-singer, Austin native, and one-hit wonder Shawn Colvin. I hate to use that term, but Colvin scored her only hit, "Sunny Came Home" in 1997.  After nearly fifteen years, it's still a great song and it will pop up on the radio for many years to come.  This is pretty cool...
