Listening to this, right after listening to her performance of this back in 2009 at the AMA's shows that giving up cigarettes made her voice a lot clearer, BUT took away that growl/rasp that made her performances so raw. Either way, love her and that voice!
This is one of my favorite songs of all times. I absolutely love her voice and her lyrics. You should hear her cover of Alicia Keys This girl is on fire.
