Is there a song for summer 2007 yet? Something along the lines of Crazy in Love in 2003 and, what, Since U Been Gone in 2005...a song that comes to identify the summer to a wide variety of people. There's been some discussion of this question, but no definite answers yet. I've heard MIMS' This is Why I'm Hot in a wide array of contexts...might be a contender, but does it have the mass popularity and longevity?
