Adam Lambert - http://www.youtube.com/watch?v=vokM1z8on5g&feature=related
Kris Allen - http://www.youtube.com/watch?v=_TQs8Ly1Y7E
Both versions sounds nice to me!
I prefer Kris's version.
Adam's version is... more of those high notes...
Kris version is v. normal.
We have to see how their other singles go...
