There’s nothing special about the song (although yes, the video did give it a huge boost for me too), but as I keep saying to myself, think of one song: Some Days Are Better than Others.
The album actually sounds a lot like Zooropa. Not sonically or thematically, but in other, smaller ways. Eno-heavy album. Opening with the title track, one that appears to take quite the large dynamic shift halfway through. Long songs. Similar contrasting light/heavy mood and feel. Johnny Cash! New sounds, but distinctively U2. Some poppy, some challenging, some fun, some gloomy. Nothing amazing, but of all U2 albums, this seems to be it's closest cousin in feel and geography.
So, with that in mind, I’m hoping Boots is like Some Days. A comparatively weak and shallow bit of throwaway fun down there somewhere in the second half, but surrounded by a Lemon, a Stay, a First Time etc.
I'm not expecting another Achtung or Joshua Tree, I don't think we'll get another one of those until all commercial pressure is off (if that ever happens), and I absolutely do not want them to re-cover 90s ground, but if they hand us an album that is of the same quality level and with such a unique and interesting feel all the way through it as Zooropa has, you'll have a very, very, very happy camper here.
i too feel this way...TOTALLY!
