It must have been, whether or not you think they've already released two crap albums.
I still want to pin him down and ask him exactly how they're going to judge whether an album is crap. If they think it's crap while they're making it, one would hope they wouldn't release it. And every album they have released is their best so far, if you listen to Bono. What are they going to go by, album sales? It's going to go platinum no matter what. Even if it gets shit reviews, people will buy it out of curiosity. (Well, maybe they'd download it out of curiosity, I dunno.) But shitloads of people will buy it, no matter what the reviews say.
Presumably, they don't mean albums that they consider crap in retrospect, or they would have quit by now.
It means nothing!! Damn you, Bono, and your hyperbole.
