I'm surprised that so far, no one has yet mentioned "Take a Walk on the Wildside" by Lou Reed, "Rebel, Rebel" by David Bowie, "I'm Coming Out" by The Supremes, or even "Born This Way" by Lady Gaga. I also think that "Girls Just Wanna Have Fun" by Cyndi Lauper in many ways encapsulates our envy of "girl world" and why we want to experience it vicariously the way we do.
On the other hand, we can't take ourselves too seriously either, and I've always gotten a kick out to Bob Rivers' "Twisted Christmas" parody of "Winter Wonderland" entitled "Walking 'Round in Women's Underwear". Who among us can't relate to that (insert honorable mention of the "The Lumberjack Song" by the Monty Python crew here)...LOL!
