It's an amazing song, but not all great songs are the best single choices, especially from Confessions.
All the songs should be together. It's hard to get the full feel of any of the songs on Confessions on a Dance Floor without the full-album experience. I feel it's best to hear each song as it fits in with the others on the album, rather than just playing a single one over and over again.
