Christina Aguilera (2007) – Best Grammy Performances

This is a man's world and Christina Aguilera is just living in it. Actually, scratch that, because Xtina took this signature James Brown tune about a male-dominated society and completely killed it in the name of all strong, independent females.

The year was 2007, and the Grammy Awards were paying tribute to the late, great Brown, who tragically passed away on Dec. 25, 2006. When the opening notes to 'It's a Man's Man's Man's World' began, everyone was pleased to see a suited-up Aguilera standing at the mic. Her magnificently powerful voice gave us chills, and she delivered the bluesy song with incredible gusto that would've made Brown proud.
