The Music Man.

OK, so I'm sure you've probably heard Susan Boyle singing "I Dreamed a Dream" on TV or YouTube, and pretty good it was, although I have to say the song doesn't do much for me, and I'm not sure it showed off her voice to best advantage either. But go back onto YouTube and listen to her singing "Cry Me a River" - much better showcase for her talent, as well as demonstrating that she can do more than simply belt out a song. And you don't have to be a looker to make it as a singer - think Ella Fitzgerald.
