5. ‘Sweet Dreams’ – Top Beyonce Videos

'Sweet Dreams' was the seventh video from Beyonce's 'I Am... Sasha Fierce' album, and she described it as more "graphic" than the others, with the intent to "take Sasha to the next level."

In the clip, her alter-ego wears a golden robot suit designed by French fashion designer Thierry Mugler and performs against a green screen with CGI effects to create a void-like digital canvas for the dance routine. With the absence of actual scenery, Bey put the focus firmly on the fashion and choreography. Proof? Those gold and diamond nail rings she wears in the video were worth about $35,000 alone.
