This just in, Madonna is still hot. I thought she had lost a little too much weight, I liked her a bit better in the "Open Your Heart" / "Express Yourself" era, but still.
I love this song too: Hung Up
But the reason for this post is how funny I think it is that she's sampled an ABBA song that was released just a year before her first release ("Everybody") and just three years before her first album ("Madonna"). Her longevity is, in fact, so great that she has made it back to the point where society and popular culture has circled back and now finds the stuff she did at the start of her career in vogue again. She's going to be sampling her own songs soon. I love it!
