McCain and Palin used Heart's '70s hit "Barracuda" at the Republican National Convention (apparently missing the irony of lyrics like "If the real thing don't do the trick, you better make up something quick"), and Heart is pissed. Nancy Wilson's initial reaction was succinct: "I feel completely fucked over." The official statement elaborates:

Sarah Palin's views and values in NO WAY represent us as American women. We ask that our song 'Barracuda' no longer be used to promote her image. The song 'Barracuda' was written in the late 70s as a scathing rant against the soulless, corporate nature of the music business, particularly for women. (The 'barracuda' represented the business.) While Heart did not and would not authorize the use of their song at the RNC, there's irony in Republican strategists' choice to make use of it there.
