MacIntyre sings a soft falsetto for most of "Keep the Faith" (from the gloved one's album "Dangerous"). It's not his best performance, but it's an inspirational song by a visually impaired guy.
DioGuardi gets the song choice: "...that wasn't the most obvious Michael Jackson song. I'm not sure if everybody knew that song, but what I liked about you choosing it's your message. This hopefully message you deliver."
And, so it would seem, does Cowell: "It's find being artistic, just not on this show," he says, dismissing the song choice because it isn't well-known enough.
