26. Usher, "Confessions, Pt. II"
Usher cycles through multiple stages of relationship grief in this 2004 video, which was directed by Chris Robinson and which features the singer in conflicted flagrante with two women before being shown the door by his lover. He works himself into such a state that he flings off his shirt, revealing his chiseled abs in shots that recall a much more contrite version of D'Angelo's "Untitled (How Does It Feel)."
