^HaHa,you finally got it.I'll have to check it out.
I think it comes down to personal preference for the two Davids.
For me,Cook is a more well rounded musician,as evidenced by his song choices.I get the progression thing.
I'm not into Archuleta's type of music,so to me,it was just one long song,no difference.I feel bad for him,I don't think he's ready for what's going to happen when he wins.I hope he grows into something and diversifies,because the tween market is fickle.And his aw shucks attitude will be eaten up alive by the music industry.
Oh and get away from Dad.
That being said,can't wait til the obligations are over and Cook gets to do his own thing.

lol.
