7. Nirvana - 'Heart-Shaped Box'
The debut single from In Utero could have almost been a snuff film and MTV would have put it into heavy rotation, but Nirvana (and Geffen) weren't taking any chances. They hired photographer Anton Corbijn to direct a creepy, Wizard of Oz-inspired video that shows an emaciated old man on a cross, a little girl in a KKK outfit and the band lip-syncing the song in a hospital bed, a forest and a tiny, bright red room. It's trippy, more than a little confusing and impossible to forget.
