Your Favorite Madonna Song?- Survey of the Day

I have to admit I am not a very big Madonna fan, but it is time to get familiar with her and her music because she is featured in one of the most popular concert events this year, the Super Bowl Halftime Show. So like her or not, what is the best song she has done?

There have been better choices for the halftime show at the Super Bowl in the past, like Tom Petty, U2, Aerosmith, and even Janet's wardrobe malfunction was quite entertaining, but Madonna? Really? I guess I kind of though the same thing about Prince, and now I consider his performance my favorite ever. That's why I am refreshing myself on some Madonna in preparation, and helping you remember some of her best stuff too. Now tell me, whats your favorite?
