'X Factor' Winner Melanie Amaro: Song Performances (VIDEOS)

When Melanie Amaro was named the winner of "The X-Factor," Simon Cowell said, "We came here to find a superstar and we found a superstar."

Given that Cowell's previous prognostications have a mixed track record -- for every Jennifer Hudson and Kelly Clarkson, there is a Taylor Hicks and Ruben Studdard -- whether Amaro ends up being a true superstar in the longterm remains to be seen. But one thing is for sure: the British Virgin Islands-born college student sure put on a show this fall.

Check out some of Amaro's top performances from this inaugural season of the US "X-Factor," including both her audition and her $5 million song from Thursday night.
