Any of the 4 would be amazing. Not a weak one in the group. Kind of feel like they need to adjust the 6th song based on the 5th spot winner. Wild Horses brought Chicago 1 to a hault after the light bouncy She's a Rainbow. Then Chicago 2 you had upbeat Shattered (5 spot) followed by a fast paced Dead Flowers. Wild Horses on works so early in the show only if it follows a fast paces sing. So Out of Control followed by Wild Horses would also take the wind out of the sails a bit.
