I think the mixes are on the right track, but don't get there.
For example, Discotheque has better song structure and a much better vocal from Bono on the remixed version. Unfortunately, the made the song too rock, and not enough dance. They took out some of Edge's finest, weirdest guitar sounds and replaced them with what sounds like typical U2. It makes the song almost bland. And call me crazy, but I love the boom-cha.
Numb I'm indifferent to because I honestly don't hear that much of a difference.
Staring At The Sun was okay, especially the vocal harmonies. But I think the harmonies should actually be louder in the mix. Also, I don't like the pronounced bass at the beginning of the song. It truly is death by mid-tempo. A strictly acoustic recording is what this song needs.
Gone kills me. Worst mix ever. The Pop version, in my eyes, was pure perfection. They totally erased Edge's wailing, high guitar notes during the "goodbye", which totally made the song in my eyes. The Bono vocal on Pop is much better. The piano during the chorus on Pop made it much more dramatic. Overall, I can't find one thing on the remix that I think is as good as the original version.
