Hayley Williams also discussed some themes in a recent Livejournal post as well.
"Most of the songs you’ll hear have to do with friendship," she writes. "In fact, this is the first Paramore album that wasn’t written mostly about love relationships. I have made a lot of friends and I’ve lost a lot of friends over the past couple years…and it’s all gonna be there for you to dissect. I think, too, that the past couple years were some of the first times in a while that I’ve felt the burn of other people’s ignorance…a lack of patience and a quickness to judge. It forced me to ‘grow up’ and realize what’s real. Who’s worth the pain and who’s not."
Their last album, Riot! was released in 2007.
