are all their albums parental advisory?

I think it is hard to tell, because the laws are different in different countries. I would suspect that they all are because they all have swearing in them, but like I said, it is hard to tell.

no not every one is! but there most recent ones are yes Amrican Idiot, 21CB, Nimord is HUGE one! that one has the most cussing in all there albums!

yes,i think so.if you own all their cd's and you look a the back,there is a possibility they are.

Most of them are depends on where you live.

no clue i think so :)
