Has your favourite band ever let you down by selling out?

The Sex Pistols have declined an invitation to play at the London Olympics closing ceremony, pleasing fans who felt the band would lose all punk credibility by participating in the event (never mind those butter commercials featuring band member John Lydon and the use of Pretty Vacant to promote the bookmakers William Hill). With this in mind, tell us about the worst examples of pop stars "selling out". Were you shocked when Bacardi sponsored Groove Armada's album? Did it sadden you to hear Thom Yorke on the Twilight Saga: New Moon soundtrack? Did your heart break when, in 2009, news came that Bob Dylan's song was to be used in an advertisement ? Or is there an artist who has earned your respect by resisting the corporate path? • Follow Comment is free on Twitter @commentisfree
