7. Britney Spears - "I Love Rock & Roll"
Much like Jessica Simpson, Britney Spears butchered a pop classic on the soundtrack to a movie that permanently ended her film career. She went with "I Love Rock & Roll" on her one and only movie Crossroads. It was written by The Arrows and made famous by Joan Jett - or "Pat Benatar," as Spears famously called her when promoting the single. People are too hard on Britney. She was close enough.
