Let's take a look back at Carrie Underwood's wonderful version of Donna Summer's legendary "MacArthur Park", famous for it's super cheesey lyrics "Someone left the cake out in the rain/ I don't think that I can take it/ cuz it took so long to bake it/ and I'll never have that recipe again." This really brings back some tingly feelings of American Idol nostalgia; I don't think I realized how special this performance was when I first watched it.
