The Song: "Isn't She Lovely"
The Artist: Stevie Wonder
Why It Would Be A Perfect Choice For The Sing-Off: Isn't it obvious? Anything by Stevie Wonder would make for a great choice for The Sing-Off, which is why we're a little surprised that only one group has chosen to use one of his songs thus far. Of course, the trick is doing justice to his original, but we get the feeling that this song would do plenty to energize the audience and the judges if done right.
