Green Day have about 45 songs ready for their next album, though presumably they'll wittle it down somewhat before releasing anything. They're very busy in the studio, though Billie Joe Armstong says he is still trying to find inspiration for the new long player, but that the current music scene isn't providing much.
Speaking to Rolling Stone he said: "We have a lot of music - something like 45 songs. It's total chaos, I want to dig into who I am and what I'm feeling at this moment - which is middle aged. We've been doing this for 20 years now. You want to make sure you're being honest with yourself. I also have to ask myself 'what's real out there?' Right now, it seems stagnant".
