"That's the moment where we said, 'This song changes everything. We're starting over right now. We're starting it over with producer Rob Cavallo, and we're doing it now'. Everything up to that point had felt like we had been in this kind of stasis, and as artists, stasis really equals death. So, it was so bad, the vibe wasn't good, and then 'Na Na' happened. And then, all of a sudden, there was this real, big intensity underneath us, and it was the momentum we needed to dig deep and record another album".〔
