This was the year the GP chose the general category nominees, right?? Oof, that was bowling-show ugly... Since I don't particularly favor any of the choices, I'll be objective and go by the one that got the most technical-award nominations:
Now: 2006
Christina Aguilera - Ain't No Other Man
Nelly Furtado - Promiscuous
Kelly Clarkson - Because of You
Madonna - Hung Up
Shakira - Hips Don't Lie
