Madonna's New Single

Madonna's still touring the world on her Sticky and Sweet tour, but she's already looking forward to her next big project. She's set to release a greatest hits album called Celebration, and the first single, of the same name, was just leaked. It sounds like a return to form for the singer, with a vibe that just might be perfect for a night out with friends. So, take a listen and tell us — does "Celebration" make you want to hit the dance floor or leave the club?
