18. Eminem and Rihanna (2010)
Eminem, in his sensitive artist phase, makes the emotional, majestic hook of "Not Afraid" even huger with an orchestra and a bunch of drummers. Unlike the wacky VMA days when he would march a bunch of Slim Shady clones into Radio City Music Hall, there's not much smoke and mirrors, but there is a lot of emotion. Eminem, performing his most severe, never puts his hoodie down; Rihanna patiently walks over, a calm to his storm.
