Good for her. If i were an actor or singer, i would take every opportunity I could. We haven’t seen the movie yet, or her take on it, so no one can say anything about it yet.
I was listening to her cover of Nashville, and around 3:24, she starts getting more powerful. And at 4:20, she belts out a note and holds it for 12 seconds. When she sang Change at the ACM awards, she belted out that note for a long time too. Her voice isn’t Broadway, I think she has it in her and will surprise us all.
