The first link is to All Time Low's music video too I Feel Like Dancin' Tonight and the second link is too Robin Thicke's Blurred Lines. There is a major difference between the use of backup dancers in pop/rap music and alternative/indie music. All Time Low are an alternative band and in their music video, they sort of make fun of other music videos. Their female backup dancers are jokingly beginning sexualised. By this I mean, yes the girls are only wearing bras and underwear and they are doing inappropriate dance moves, but the reason All Time Low has them doing this is because they are making fun of the typical music video where this happens. But in Robin Thicke's video for Blurred Lines, the backup dancers are completely oversexualised on purpose. The girls are all in small, tight clothing, and there are some scenes of them almost naked. The dancers are shown licking their lips and doing other inappropriate moves with their bodies and mouths to the men. In most videos in alternative or indie music, there are either no backup dancers at all or if there are, they are rarely doing inappropriate things. While often in pop or rap videos, the backup dancers are doing many inappropriate moves.
