Lose the Dido Already

Last night I caught the preview of the new movie "Becoming Jane" for the first time. It was well done-lots of shots of Anne Hathaway's teeth, a funny cutting remark from Maggie Smith-but once again, like with the trailer for "Evening", the backing song was one by Dido. (This time it was "Don't Leave Home".)

What is going on here?

Do they think we won't know it's a chick flick without that audio clue? Do they think that a Dido song is the trigger that will magically open our purses and get us to the theater?

I got news for you Hollywood-you had me at Jane Austen with this one but you lose serious points by falling back on stereotypical lazy musical shorthand. Please, music-wise let's move on.
