First impressions on "Hung Up"--since I know you're all waiting with bated breath.

1) A great sample. It's a perfect example of how a sample should be used--it's there just enough and it's not like it's just Madonna singing over ABBA.
2) A wonderful return to pop music by Madonna--and pop is something she does so effortlessly. Say what you will about American Life, but that album was decidedly not effortless. It's an album that I end up having to make more excuses for than anything else. I think this is going to be decidedly different.
3) I love the throwback to the Prince duet from Like A Prayer--"Time goes by so slowly for those who wait and those who run seem to have all the fun."
4) I think it's going to be huge in the clubs. I still can't quite decide whether radio will pick up on this or not. For her sake, I hope they do. She can't really afford another commercial failure.
5) And I agree with what someone posted on a Madonna message board--"Hung Up" did the impossible--it made "Gimme! Gimme! Gimme!" even gayer than it already was. *hehe*

It's been played 5 times on my iPod and 8 times on iTunes. And I'm sure it'll get played a lot more in the weeks to come.
