Song Question and Personal Analysis

I recently watched the movie for the first time and I enjoyed it. It was a very true to life story. Even though Nicole has had her heart broken, she does what most women do, she finds and sleeps with a "rebound guy." Although the movie doesn't focus on him much after that, we know he will be hurt in the end also. I detest stereotypical Hollywood movie endings, but this one was realistic. She realizes that she must move on and begins to get her life together. True to life, Robbie eventually realizes his mistake, but it is too late. By the way does anyone know who sings the song "Champion" from the movie's soundtrack? It contains the lyrics, "...a champion moves on..." in the chorus.
