What is unsurprising is that Lady Gaga took the top spot. The pop singer has had an extraordinary year; winning Grammy's, rocking the Billboard charts and revolutionizing the music industry. Cyndi Lauper said about Gaga in the article, "Most of the stuff on the radio is not very clever, but Gaga presents her ideas in a sophisticated manner. She has an incredible pop sensibility." We agree, and wouldn't be surprised if 10 years down the road Gaga is labeled one of the most influential people of the decade.

Those rounding out the top five also aren't very big surprises: Conan O'Brien (who probably wouldn't have made the list if he wasn't booted from "The Tonight Show" and hadn't rallied accordingly), Kathryn Bigalow (the first female director to win an Oscar), Oprah Winfrey (duh) and Valery Gergiev (an influential Russian conductor and opera director).

"New Moon" director Chris Weitz spoke in Rob's honor to Time, saying, "So how to write about someone who seems to answer Freud's rhetorical question, What do women want? Perhaps it's just worth pointing out that it'd be fun to have a beer with him even if he weren't Edward Cullen. That we haven't seen a tenth of what he can do onscreen. And that important things, beyond the veil of Hollywood, occupy his time too music, conversation, ideas, a sense of the absurd. Which, maybe, explains why he never gets to my e-mails. I love you, Rob! Call me!"

Taylor Swift also got a nod at #9, thanks to winning some major Grammy's and also having her film debut (yes, in "Valentine's Day"). Stevie Nicks, who performed opposite her at the Oscars, compared her to Neil Diamond and Elton John, and said, "The female rock-'n'-roll-country-pop songwriter is back, and her name is Taylor Swift. And it's women like her who are going to save the music business."

Rounding out the list is Sandra Bullock at number 22, and while we agree with the decision to include her, we're almost a little sad to see her this honor in light of everything that happened recently to help her deserve it.
