Query: NOT BAD...

This is my second Green Day album (American Idiot being the first) and i really do enjoy it. Especially songs like Geek Stink Breath and Brain Stew/Jaded. However, this album is just different in a way i can't explain how and it is rather short. i guess that just goes to show how much the band has changed and matured. Still a good album.
