What's That Song From the 'Eat Pray Love' Movie Trailer?

'Dog Days Are Over,' Florence and the Machine

After seeing the trailer for the new Julia Roberts flick 'Eat Pray Love,' viewers will probably be thinking two things: "Is Julia Roberts still a 'Pretty Woman,' or what?" and "What was that infectious song playing in the background?" Though the first question is rhetorical, the featured tune would happen to be 'Dog Days Are Over,' by Florence and the Machine.

The lyrics to 'Dog Days Are Over' parallel the plot of 'Eat Pray Love' perfectly. The film, which is based on the best-selling memoir by Elizabeth Gilbert, chronicles the travels of a recent divorcée on a quest to find peace and happiness. Roberts stars as author and protagonist Liz Gilbert, who travels to Italy, India and Bali after realizing that her cookie-cutter way of life isn't bringing her any joy. She decides to travel to these three countries in order to eat delicious food, pray and meditate about her present state of being, and to find true love.

Serving as a mirror to the storyline of the movie, the opening lines of 'Dog Days Are Over' read, "Happiness hit her like a train on a track." The percussion-driven song was written by frontwoman Florence Welch and fellow band member Isabella Summers. "For me, 'Dog Days' symbolizes apocalyptic euphoria, chaotic freedom and running really really fast with your eyes closed," Welch told USA Today. Welch's powerful vocals add the to depth of this unbelievably catchy song, which was co-produced by James Ford of Simian Mobile Disco.

Florence and the Machine are on the fast path toward international stardom. The English soul rockers' debut album, 'Lungs,' was released in the UK in July 2009 and in the US in October, and has been praised by critics and fans. 'Dog Days Are Over' has also been nominated for four MTV Video Music Awards, including Video of the Year and Best Rock Video. Florence and the Machine are scheduled to perform at the award show on Sept. 12 in Los Angeles.
