58. Eminem feat. Dido, "Stan"
Eminem's scariest song because, for once, the horror seemed real. Anchored by a sample of U.K. singer Dido's "Thank You" (which also became a hit), the song followed an obsessed fan who acts out Em's deranged fantasies. "I try to help him at the end of the song," Em said. "It kinda shows the real side of me."
