I don’t think there was any theme to the album, they’ve been pretty forward on the fact that Cigarettes & Valentines was just a solid power pop punk album, likely taking what they had been doing with Warning and mixing it with some classic high energy Green Day. It was good, but not “global phenomenon” good, which is what they needed at the time. The album was basically a rehash of what they had already done in the past, so of course the “American Idiot” concept won in the end. As people have been saying, Cigarettes and Valentines truly is the missing link between Warning era Green Day and American Idiot Green Day, and I think that’s whats so appealing about it. What COULD have been.
