I did not expect that Leighton Meester and Garrett Hedlund could sing, but they do really well. Their voices are amazing for country. The chemistry between these actors is so sweet and fresh. Thus I can say that I love this movie and this couple. Moreover, I did not like the performance of Gwyneth Paltrow, so static, and her voice is not the best one to play the role of a huge country singer. But it was not so bad.
Music is awesome, specially Leighton and Garrett's songs. I really liked this movie.
