"Hung Up" starts off with samples from ABBA's "Gimme! Gimme! Gimme!" to jump full fledge into a track that you simply will not be able to sit still through.
God damn, that sample is waaay too catchy! And it's disco! Someone help me!
On an unrelated musical note, I placed an advance order for the new William Orbit CD (first new one in 5 years!), and noticed the new Beth Orton CD is coming out around the same time, so I took a (small) risk and ordered it too. Plus, the new Lemon Jelly (which I've already enjoyed on Hayoo! Music) The final track on Lemon Jelly's new CD features William Shatner, so you know it's good. (Check out Shatner's album "Has Been")
