Starting with her "American Idol" win, Kelly Clarkson has been a trailblazer her entire musical career. And while she was on tour with The Fray in September, she shook things up again. Instead of having fans scream the songs they wanted to hear at her shows, she had them to tweet her with the hashtag #KCrequests. Interestingly, her best viral video has been a cover of Katy Perry's "Wide Awake." And that's the power of social media: By using Twitter you get to keep your voice and still remain engaged in the show.
