Gone is in my top 2 from POP, and as I think we can almost all agree here, would have been the best choice for the first single, or at least A single.
The New Mix is good. I really like the first half or so. Where it loses me is at about the 3:20 mark. The "No emotional good night... and after.
It just doesn't hold the emotion of the album version. And overall, the album vocals are just more loose and real to me.
Lots of what makes U2 songs great is that intangible feeling you get. And the album version just has that feeling that i don't fully get on the new mix.
Either way, the song would have KILLED as the first single, either mix.
